I haven't received this error before and I don't remember where I used BigInt, and it didn't specify a file. When I delete the application and run it again, the application opens, but when I run it from time to time while it is open, this error appears and the screen freezes in the splash screen. I have to delete and reinstall it to run it.
I couldn't try anything because I couldn't determine where the problem was.
