I am unable to provide a screenshot of the issue, because this caused my world to become corrupted when failing to save. My backup is smaller in file size (my other backups were deleted accidentally when I was troubleshooting) and it would take me a decent amount of time to increase the file size enough to cause this error again. Not saying the issue is fixed now, as I know this error will happen again if I continue playing on my backup once it grows large enough, because this has happened to me before. Essentially there's no point in me playing on my backup that isn't corrupted until this issue is fixed, because I'm worried it will start failing to save again and then cause my backup to corrupt.
Game is unplayable on my world. This only affects worlds approaching 1gb (953.1MB).
Might as well just forget about bedrock and start playing on Java.
