Mac mini 2018i7 (Macmini8,1) with broken Bluetooth since upgrade to MacOS Montery

I am unable to turn on bluetooth on my Mac Mini 2018 since the update from Big Sur into Montery 12.1, 12.2. 12.3 and 12.3.1 The Bluetooth has been broken! Tried resetting the SMC and did a clean reinstall of Monterey and performed a downgrade to Big Sur without any succes.

Apple Diagnostic doesn't show any error.

When I check the system report

Bluetooth Controller

State: off

Chipset: BCM_4350C2

Discoverable: off

Product ID: 0x0001

All suggestions as mentiod in a simulair thread did not work, so who has found a solution?

Hey MacWalker-NL,

It appears that you're having a problem using Bluetooth with your 2018 Mac mini. Great job on the troubleshooting you've tried, and we're glad to provide assistance.

New user or group setup - Apple Support -- Even though this sounds like a hardware issue, we want to be sure. Please create a new Administrator account. Log out of your own and into the new one and check the System Report from there.

Get Support - If the Bluetooth Address still equals NULL and the State and Discoverable are off, we recommend contacting Apple Support to look into this issue further with you.

All the best.

Thanks, I have created a new Administrator account. Restarted the Mac mini and the BT problem has not been resolved. The address is still NULL. There is another thread Macbook Pro A1708 Bluetooth Issue - Apple Community with the same BT problem with the chipset BCM_4350C2.

Question: is Apple accountable for the damage to my Mac mini for the Monterey upgrade that bricked my BT?

The upgrade to Monterey to another Mac mini with the chipset BCM_4364B0 was successful.
