QR code looking thing shows up when I try to run the game in editor.

This set of errors have been bugging me for nearly a year now, I can’t find anyone else that had an issue similar to this. What I know so far is that, it’s compatible with version 4.26, the project is not corrupt or anything and the last doubt I had was that it might be because of the drive letter, which turned out to be false as well. Could anyone help? I’ve put a solid amount of work into this project and I wouldn’t like to lose all that progress.

Looks like you’re trying to access null references and trying to access elements from an invalid index in an array. If you click on the last link in an error it should take you to the point in the blueprint the error is happening. The QR code looking thing looks like random noise to me, which is probably because you’re rendering an uninitialized texture which just has some random data in it.
