No issue with SafetyNet on my Mi 9T but I'm on "Stable ROMs" branch now... ^^
If "ctsProfile" is failing now without any reason, It certainly means Google revoked the ROM's certification (by mistake?...).
You can wait 1 or 2 day(s) or you can reboot your device and check SafetyNet again or you can, with Magisk, try fixing this issue with the "MagiskHide Props Config" module.
== Guide ==
Find "MagiskHide Props Config" module in Magisk app and install it. Reboot your device and follow these steps:
1. Download/Install
Termux app =>
Termux-0.117.apk
2. Open Termux app, type "
su " and hit enter (Termux will ask for root access => Grant it)
3. Type "
props " and hit enter
= Wait a few seconds =
4. Type "
1 " and hit enter to edit device fingerprint
5. Type "
f " and hit enter to pick a certified fingerprint
6. Type "
30 " and hit enter to chose "Xiaomi"
7. Type "
21 " and hit enter to chose "Xiaomi Mi 10 China (10 & 11)"
8. Type "
2 " and hit enter to chose "Android version 11"
9. Type "
y " and hit enter to confirm it
10. Type "

After reboot, clear all data of
Google Play Store ,
Google Play Services and
Google Service Framework apps in phone's settings
then reboot your device.
