Crash/restarts when playing with Bleutooth (using Microsoft BT mouse, crashes Librem5???)

Hi, trying to pair a Microsoft keyboard and mouse here, but I fail because it either takes ages that my phone comes with a message that the mouse will pair (but never succeeds), OR the phone just crashes/stops. And I have to start it again.

Same with the keyboard.

Also tried to pair/trust via 'bluetoothctl' but same result: none :-(

If I'm correct earlier I had my Logitec mouse/keyboard with unifying dongle working but that one also fails now.

Willing to move to using mouse/keyboard (and hopefully a monitor), but all my trials fail (having a Dell K17 Dock here lying around also crashes the phone). Any hints on something that should work?

I recently (like 10 days ago or so) reflashed my phone.
