Upgrading to 4.18/4.19 Crash

Hey guys

I have a project that I need to upgrade to either 4.18 or 4.19 but when i upgrade the project it crashes on startup. The project works flawlessly in 4.17. No crashes, no errors and i can even package the project without a problem.

Any help would be massively helpful, I will attach my logs here.

Thanks guys
