New Bluetooth app crashing since Miui 14 update

[arli21]

Hello,

I recently updated my Redmi Note 11 to the latest MIUI version, and my Bluetooth does not work since then. I am met with a "Bluetooth keeps crashing" screen at startup, in the control center it hangs on "Turning on", and in the settings the slider turns blue but nothing else happens.
The crash details :

Spoiler: Details

I am having the same problem. The crash details are the same

A temporary workaround has been to switch SELinux to permissive -- switching it again to enforcing afterwards keeps the Bluetooth working. I have also reset Bluetooth settings, I don't know if it helped.

But it would still be nice to fix the bug

I have 11T and have the same issue when pairing a newer bluetooth headset. Could you guide me on how to fix this? I have MIUI Global version 14.0.4 currently.
Thanks!

You'll need a rooted phone, then you can use an app like this one : The SELinux Switch v7.1.4

Could you let me know what this app does and what "Switch SELinux to permissive" means? It was awhile ago I rooted phones, last was back 10+ years ago
