so the unable to fast travel bug has now truly ended my fallout 4 experience i cant fast travel out the institute, so im simply stuck and can not continue, this bug is simply not good enough, so many people are having this issue and bethesda wont even respond to my email, what a waste of 39:99

still no reply from bethesda...

If you go to the place you teleported in to the institute, you can find a yellow button that allows you to teleport out. However, there is no way back in as your fast travel will still not work. I am experiencing the same thing.
