can you try with the latest BlueZ 5.49 or git version. Seems it actually stumbles over the extra packet here. Fun fact is that I can not get a backtrace to pin-point the issue in btmon and why it crashes.

Why do I see only HCI events here? Is this event conveying any useful information. It is kinda complicated that this is 0xe4 event code which is actually reserved for future use by the Bluetooth SIG. Are there any accompanying HCI commands for this and they just not make it into btmon?

Here it looks like you have 0x006f opcode with first octet 0x01 for command and then vendor event 0xe4 with first octet 0x02 for event. I assume the second octet is then the vendor command code for these.
