Hi,
Are you saying you are able to reproduce this bug with a new project? If so could you give me the exact repro steps?
On my side I’ve created a new ThirdPerson project (non c++) and saved the default map as a new map and set it as the default map in the project settings but I’m not hitting the crash.
EDIT:
I managed to repro this and the issue happens when the default map for the project is renamed (uses a redirector). The issue will be fixed in the main branch but in the meantime you can use the Fix Redirector on the map in the Content Browser to fix this.
Cheers
