hi @beibs_in_da_trap

Assuming you can run the original published version

Restart you PC as the 41.00 update needs a restart

Run Verify and then try disconnectiong revsion control then reconnecting the project to revision control.

My system recevied another patch at 12:00 UTC (2 hours ago) so that why you need to run Verify from Epic Games Launcher.

Looking at the error message you are having trouble with “lores” in Revision Control and there was a possible answer in this thread, which you could try while waiting for Epic Support
