Are the errors red errors, or warnings? I found when I was working with an older Godot project, there was a ton of "errors" in the debugger that turned out to be GDScript style warnings. It said a ton of errors were dropped, which was quite confusing until I figured out what was going on.
Having released Godot games with errors, it likely will not crash when you export the game. However, it may print to the console in the exported game, which may or may not be desired.
What are the errors showing? Do they point to a specific line in the code?
(edit: I slightly modified the original post to replace the swearing.)
