Officially not, but you can try this solution, it worked for me a year ago:
Make a backup with twrp
Flash a the weekly
Let it boot, it will be a 'clean' install
Reboot in twrp and restore only the data partition.
There will be some minor settings you have to setup, but most apps...
I fixed it by going into developer settings, 'Feature Flags' and turned settings_bluetooth_while_driving to 'on'
It was disabled. After that, AA worked.

Could you flash the latest weekly after restoring the data partition, and clear cache and dalvik? If that does not help, I think a factory reset will be the only solution unfortunately. I tested the Hotspot on my mi 8, and it works fine after this workaround.
