My matlab 2020b will flash on the taskbar but never opens. We have tried reinstalling and there are no mathworks or matlab processes ever running on the PC to close. My IT administrator has givem me admin rights to try any solutions but thus far I have found none on here.

I had no preferences in the 2020b folder. I made one and matlab still didnt open. I also have no startup.m file

Matlab cannot start without a preferences folder. This folder contains some files, which contain important data. You cannot simply create such a folder manually.

See: prefdir

This has been resolved, my department had my license assigned to someone else, and I was using another users. Once I did a clean reinstall after the license issue no problems. Thanks for your help.
