Diamonds bug? | Geometry dash 2.11

My Geometry Dash account currently has a fatal problem. I only collected stars, but suddenly the number of diamonds reached 700 million. The details of the incident are in the video. I was hoping I wouldn't make a video with this issue, but I did because it hasn't been fixed for quite a while. 2.2 is coming soon, so if this doesn't work out, it gets pretty tricky.
