Ue 5.4.4 error when trying run

I’m having this problem while trying to get my project up and running.

Anyone know maybe how to fix it?
I changed the GPU and reinstalled the system under the new branding (AMD to Nvidia)
The game is on an external drive, once I managed to launch it after the system change.
Today when trying to launch I got this error

GPU drivers: current
RAM and Disk: Valid

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x0000000000000000
