So, and the TEESimulator crash only after make a test with Duck Detector right?

I think some of the test broke the keystore service and for this happen.

I'm also on a ROM based on LineageOS (/e/OS) which use MicroG instead of Google Play Services.

Yes noticed recently

Yes

Exactly like the posted video, but the latest version of duck detector alpha,

Tee simulator working, key attestation ok, open duck detector, first it detects bootloader unlocked, open key attestation or play integrity checker or any app require key attestation for check bootloader it won't work

I tried using custom keybox implementation in my rom and it works no problem when launching duck detector

Didn't try tricky store as I don't trust it anymore after closing source

I have microg just for morph YouTube but the device using gapps
