Matlab 2021a freezes on startup for ~5 min, then becomes responsive

11 views (last 30 days)
When I startup Matlab2021a on my Win10 machine, the program works fine for the first 5 seconds, but becomes totally unresponsive for ~5 mins. After the 5 mins, I am able to use the program normally. Its very annoying to have to launch matlab and wait for it, I don't remember having this problem in the past on other laptops.
My license for matlab comes from my university, perhaps there is some delay in checking my license?
Any help is welcome!

I recently uninstalled and reinstalled Matlab, and when I run the commands above I get this output (in red text):
No value is set for setting 'History' at personal level.
I did just notice that the files I am working with appear greyed out while Matlab is frozen, then come back when it wakes up.
These files are saved on my C drive though, so it shouldn't be trying to sync to a network drive.

What you are observing is not normal. However, I do not have any more ideas as to what the problems might be. You should probably contact Mathworks, as this is effectively an "installation" problem.
