I haven't played the game in a very long time, years probably. Everything up to date that I know of, and the game is unmodded. For some reason I can't use the alchemy tables. I get the introduction message for using one for the first time, and the animation plays, but when I attempt to exit the alchemy table or create a potion, it freezes at the "potion created" "creation failed" or "do you want to exit the alchemy lab?" message screen. The first few times I was able to use the console command "kill" to force exit from the table, but now my character isnt even targetable when I open a command line.

It is only alchemy tables. Work benches, forges, enchanters, grindstones, and cooking pots work just fine.

Turns out I cant use anything at all. Everything else I can at least exit from without crashing, but if I actually attempt to make anything, it bugs out. It worked fine yesterday,

Try loading an older save and see if you can do alchemy, enchanting, smithing, etc. with it. If it works with an older save, then the one you're using is corrupted.

Does it do this on an earlier save? Or a new character?
