Fatal error! Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x0000000000000208

Hello, i was working on an update to my game (it worked fine before), and when i packaged it, then i opened the exe and it keeps giving me the “Fatal Error!” message. I think it may be something with the fact that i changed from UE 4.26.2 to 4.27.2, but idk. Any help would be very greatly appreciated ASAP.

The error message:

Fatal error!

Nvm, fixed it, turns out it was the update to 4.27.2, so i just downgraded to 4.26.2 and luckily i had a 4.26.2 copy, or it was something else, not sure. Yippee! Only lost half an hour of progress. Not bad.

It looks like a function was renamed between 4.26 and 4.27.
Guess you’re not using C++? If this is the Launcher version of Unreal you can install the optional Engine Source and Editor Symbols for Debugging and that error would show you exactly where the problem is. As in which line and in which line.
