It's a phenomenon I've run into before and I know it's mod related. However, this time it wasn't the mod I suspected.
I'm talking about losing your ability to interact with the world. You can't open containers or doors or talk to the NPCs.
clicking, spacing does nothing.
Is there some fix or work around for this? Or are people even familiar with it? I've had this problem in past but I've
never found a topic that directly addresses it.

Have you tried just saving and reloading?

Try opening the console and typing "enableplayercontrols".

Yes, I've done the save & reload thing, However, I was unaware of that particular console command. I'll have to go back and test that out. Thanks.

It sounds like some sort of script where something is supposed to play out in front of you and you aren't allowed to do anything, like when the Emperor is murdered. However, if nothing is happening, it's hard to tell what is causing it. You may want to try Shademe's runtime script profiler, you would then at least get the form ids of all the mod created scripts running. Then all you would have to do is look at the first two digits of the form ID and compare it to your load order in wrye bash, and then hunt down te script using TES4Edit. This is not an easy method, and it is quite time consuming, but it's the only method I know of.

I'm not "paralyzed". I can can still move freely. I just can't interact with NPCs, doors, containers. This is confined to an obscure corner of the game. Since I couldn't talk to the person I needed to, I just forced the next stage with the console.

Do you have any mods that touch that area?

I know Integration, and Viconia both have NPCs in Bruma Dungeon.

Yea, Feldscar touches Jorundr. Yet, I disabled it and its patch and the glitch or whatever still happended.

Is it possible that you hit some variation of the (in)famous Bruma Statue Issue?
Try to download the Update My Statue mod (Nexus), install it, do what readme tells you to do and revisit Bruma.
I had a CTD constant problem which this mod solved for me.
After you complete MQ, you get statue in Bruma.
If you had mod-added aromor/clothes when talking to Okato, game goes weird if you try to enter bruma 3 days later.
The UMStatue mod sorts this for me, could help you.

Statue bug won't affect the interior of the Bruma dungeon though. Also, your statue is built upon returning to Cloud Ruler, it has nothing to do with Ocato unless you've got a mod that changed that.

Feldscar only provided Jorundr some additional dialogue, it doesn't directly edit him or his other quests, and there's no scripts in there to lock out the player controls.

Nonetheless, the second I went thru that door I was toast. In the end I just worked around Jorundr with the console.

You never know what kind of whacked out interactions these mods are going to have. I just had another issue.
My game started crashing ever time magic was used on me. I disabled Lethal Majesty and all was well. I mean,
how is a clothing mod connected to a magic effect? My char wasn't even wearing it when this was happening.

It's possible the mod might have had some unintentional dirty edits, and due to the load order, was counteracting the mod that dealt with magic.

I'm finding myself really leaning towards an overall modding concept of selecting mods that only focus on specialized areas, instead of ones that make changes over several areas. If you are going to go with an overhaul, that's fine, but don't get too experimental with additional mods that have not been signed off for compatibility.

Which still has nothing to do with the statue, since it's not even in memory anymore by the time you've made it to where Jorundr is. Something else is causing you the grief here, and it isn't Feldscar either.

You'll probably need to sit down one day with TES4Edit, load everything you're using into it, and then find the data for the Bruma Dungeon and see what's referencing it. You may just be surprised.

The clothing mod may contain edited or custom meshes that react badly to being struck by magic due to some misconfiguration in the collision data. There's been other reports of similar problems with getting attacked by NPCs and creatures wielding certain mod added weapons. This sort of thing svcks to troubleshoot because it won't have something clearly marked in the ESP file you can anolyze with TES4Edit.

I certainly don't blame the statue. That's a non issue since I haven't done the MQ in my current play through. Right now I gotta watch the
calendar, make sure I don't miss the 15th or is it the 14th? For the longest time, my months have been starting on the 0th day That, and
I can't see the IC . As long as the game doesn't just collapse and become unloadable like my MW game.

The exact same problem happens on a regular basis with Reznod's Mannequins. Anytime you place a mannequin, most of your player controls are disabled. The only way to get them back - that I've found - is to try to jump once; then everything is enabled again.
I have no idea if this will help, but looking at what RM does at the point a mannequin is placed may help you track down what is causing your particular issue.

You have months starting on the 0th day? That's not good...sounds like your savegame does indeed have some issues. Hopefully it's not too corrupt to keep playing...
