It seems I found a solution that has worked for me (for now?)
First I recorded several logcat logs:
defaultuser in š Xperia10III in ~ as š§
š āÆ while true;sudo appsupport-attach /system/bin/logcat | grep -E 'system_server|AndroidRuntime' | tee ~/$(date +%Y%m%d%H%M%S%z-logcat.log);find -maxdepth 1 -iname '*-logcat.log' -empty -delete;sleep 1;end
<lots of output>

š āÆ ls

I then grepped for the OutOfMemoryError:
š āÆ grep -A30 'OutOfMemory' *-logcat.log | grep 'OutOfMemory\|\bat\b'
And this UsageStats thing kept popping up:

So I searched for files or folders named usagestats:
š āÆ sudo find /home -type d -name "usagestats" 2>/dev/null
/home/.appsupport/instance/defaultuser/data/system_ce/0/usagestats
As nothing was working anyway, I thought Iād just move that directory out of the way, while stopping the appsupport completely:
š āÆ sudo systemctl stop appsupport@defaultuser.service
š āÆ sudo mv /home/.appsupport/instance/defaultuser/data/system_ce/0/usagestats{,.bak}
š āÆ sudo systemctl restart appsupport@defaultuser.service
After that, I can use Android apps as usual, no crashes.
