Hello, I am trying to start the unreal engine version 5.3 and every time I create a new project or try to open an old one I get this error, does anyone know how to solve it?

Assertion failed: Module [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Private\Modules\ModuleManager.cpp] [Line: 397] OutputLog

Greetings @jamieb

Welcome back to the forum! I’d be happy to look into that for you. Can you provide a crash log and your current system specs? Thanks!
