Studio 2017 freezing every day

Hi,

so for the last two weeks or so I've been having the same annoying problem each and every single day: at some point of the day Studio will freeze when trying to either type in or approve a segment, and will not come back to life. After shutting it down (via Task Manager, otherwise impossible) and when trying to relaunch it, it will freeze on "Loading plugins" and no progress is ever made. The only thing that helps is to reboot the PC.

I use Windows 8.1 and no system update has been installed in the last month, I checked.

Does anybody know what can be wrong and how to fix this????
