[Android Q&A, Help & Troubleshooting] euschen:
Hello everyone,

I hope thats the correct forum to post this question. I tried to find something through google search but it seems that there are only some stackoverflow development questions on that topic, which do not help a lot.

I have a MI9 (MIUI Global 10.2.30 stable) without root. Now I wanted to remove some default system apps and found this tool here: github.com/Saki-EU/XiaomiADBFastbootTools/releases/tag/6.6.2

I followed this list (and tailored it to my own needs): gist.github.com/Biswa96/81fe477079fa5279f7cfd7b98d5519c7

After finishing my de-bloating I realized that Google Calender (and also system calender) does not start any more. All I get is the error message "Failed to find provider com.android.calendar for user 0; expected to find a valid ContentProvider for this authority"

I tried to reinstall Google Calendar (and also all the removed bloat apps) but it doesn't help. Here is also the log file from adb logcat:
