I think this is a regression.
The commit (Asterisk11) 1943cfc53cadff36e64704257c06590bceca459b is problematic.
I experienced the same problem and reverted this commit.
Now everything is ok.

You can try this change:
3669		if (call->member->in_call && call->lastqueue->wrapuptime) {
to:
3669		if (call->member->in_call && call->lastqueue && call->lastqueue->wrapuptime) {

> After upgrading from 11.19.0 to 11.22.0, we've all of a sudden started experiencing frequent segmentation faults related to the can_ring_entry() function in the app_queue module. 
> I've attached the backtraces of 3 crashes that happened in the space of two hours on a system with a load of about 1000 peers and 80 simultaneous calls.
> We use both realtime queues and queue_members. We've reverted to 11.19.0 on this system for the time being.
