So if I understand everyone is sounds like Studio is freezing. So you are not getting the dialog Studio has unexpectedly quit, but a completely unresponsive application.
Just as a precaution can someone attempt to disable all their plugins and verify the issue persists.
If anyone has time to try out the steps here How to post a Bug Report - #13 by Roblox to send me a dmp file via “How to generate dump files for freezes/hangs” that would be hugely helpful.
A short youtube video or screenshot of studio right before/after freeze would also be helpful.
