Hello there @StephenCuthbert!
The error you are encountering has popped up in other threads accross the community, and it’s usually tied to corrupt, missing, or invalid assets in the project. Let’s tackle a few ways to resolve it:
First step, the most simple, open a new map, to ensure the crash is isolated to that project, and not a general issue with UE
Go to your project directoty and delete the following folders: DerivedDataCache, Intermediate, Saved, and Binaries
Check for any recently added assets, especially custom or FAB elements, and disable them from engine (use the alternative map, since your project is not opening)
Rebuild the project from Visual Studio, via right click right-click your .uproject file and selecting “Generate Visual Studio project files”
If the issue persists, please send us the extended crash log, which can be found following this guide: Crash Reporting in Unreal Engine | Unreal Engine 5.5 Documentation | Epic Developer Community
