Every time I add to project a FAB, it crashes after (sometimes also not) dowloaded it.
Plugins
Add to my content browser the FAB

I tried many things but, thanks to Chat GBT, it was an external problem: they were the video driver that were corrupted or old that made me crash when I was importing from FAB plugin. I simply clean the video drivers (AMD Cleanup Utility) and reinstalled everything and it worked perfectly.
