Google services stopped syncing after the device having less than 10GB space

Basically the title.

Is this only OnePlus/OxygenOS/ColorOS issue? I didn't fine any solution/workaround.

Now I don't get notification for new email (gmail) and google calendar event. I have to refresh manually. Google contact sync stopped working at all. Even I sync manually, it doesn't work.

I searched online. I can see this issue is not new at all. I can see post from 2020 as well. No fix till now?
