This has been happening to me for a couple of months now, it’s very problematic for me. When I try to install plugins they fail and throw errors as well. Uninstalled Unreal, the Epic Launcher, and even reset windows. Nothing has worked. Also, the new UE 5.8 is having an issue where projects I create in it don’t recognize what engine version they are, and on the thumbnail it says OTHER instead of 5.8… at this point I’m just tired. I’ve become disillusioned with Epic and find the whole thing exhausting, my experience with unreal and the epic launcher has gone downhill since “Fab”.
I also have this issue, it pretends to update but does f all. On next open launcher it again wants to pretend to update stuff. Additionally it keeps asking me to associate project files which regardless of accepting is asked the next time also.
But these are all super minor issue compared to the dumpster fire that 5.8 has been for me in the amount of deal breaking bugs.
