Well this is new for me, when Everest was restarting I accidentally clicked inside of the black window and then just nothing appeared in that window for a while so I closed it, reopened Everest and it gave me this:
#Everest startup crash
severe dome
steel quarry
verify game files and reinstall everest
static sandalBOT
Steam Instructions
Epic Games Store Instructions
If you have Everest installed, you will need to reinstall it after verifying.
severe dome
