Engine freezes when I click on "run game"

So, I’ve only worked with the Unreal Engine 5.3 for a few months, but so far it mostly went without technical problems.
But since today the Engine freezes, when I click on the button to run the game. The rest of the computer works just fine, but I can’t interact with the engine anymore and have to close it with the taskmanager.
I already tried to patch my project to the version before the crash, disabled motion blur (I read in a forum that it might help with freezing) and restarted and updated the PC.
Has anyone experienced something similar or knows where the problem could be?

Hi @Akutos
Let’s see…
Check Logs: Look at the Unreal Engine logs for error messages.
Test with a New Project: Attempt to determine if the problem is reproducible with a new project to rule out file corruption
Update GPU Drivers: Update your graphics drivers.
Disable Plugins and Reset Preferences: Disable plugins and reset editor preferences to their default state
Clear Cache: Clear the Derived Data Cache in AppData\Local\UnrealEngine. Rebuild it.
Rebuild C++ Solution: When coding in C++, delete Intermediate, Binaries, and Saved folders and then rebuild.
Reinstall Unreal Engine: Reinstall the engine if files have become corrupted.
Check Hardware: Monitor system resources for any overloads or overheating.
Try Downgrading: If the issue started after an update, try reverting back to a previous version of UE5.
