Marmoset Toolbag 4 crashed and now it never works

Lacasitos

So i was working with MT4, nothing special, just using the default materials and then it froze, I waited and waited but at the end i used the Task Manager to close the app and now id doesnt work at all, i cannot open any project or start a new one, it always freezes instantly.

I've tried re-installing, removing every single folder and using admin mode, but nothing.

I wrote to the Support but looks like they are really slow reading the cache files or they are really really busy
