I played around with UE5 when it was in early release. I was able to create and open projects without issue. I havent touched it now for a month or 2, but now in release I can no longer open projects I just created. During that time there was an update for a new major version of Mint so there could have been something in that update that is causing my issue. Or it also could have been a change in the engine code. Opening the engine and creating a project work fine. Once its created it crashes while opening it.
