Adding and removing shaper repeatedly causing interface crash

Description
Since at least one other user confirmed that, filing the bug here - relevant forum thread: https://forum.pfsense.org/index.php?topic=88675.0
0. Make a backup of your shaper settings if you have some in place, remove the shaper after that.
1. Go to Firewall - Traffic Shaper - WAN, set up a quick shaper like this
(The bandwidth does not matter for this test, can be empty as well.)
2. Browse for a minute or two to check that the shaper is in place and works (Status - Queues).
3. Remove the shaper.
4. Wash, rinse, repeat steps 1-3 a couple more times if still alive.
This managed to kill WAN in 3-4 cycles on any box I tried. PPPoE with DHCP, cable modem with fixed IP, ... does not matter. (Probably "works" with other interfaces as well)

About a month ago I tried to set up a shaper on the LAN interface and got a similar result. The web interface was blocked, no traffic flowed on the LAN interface but the other interfaces continued to work properly.
I was unable to properly debug this as after I got locked out, but it appeared that some configuration files had been corrupted in the process, because after a reboot, the web interface no longer started, complaining of a missing group, which was confirmed since the group file was now missing.
I restored a 2.1 system image backup and restored an old enough configuration in order to restore service and investigated no further.

I guess you had to power cycle the box some time after getting locked out, so maybe the group file missing on bootup in that case is https://redmine.pfsense.org/issues/4519 "Full installs are suffering disk corruption on reboot/power loss".
So you suffered from both this Traffic Shaper issue, then issue 4519 as a bonus :)

I frequently see this bug as well.
A reliable work-around I use is to first Disable/Uncheck & Apply then finally "Remove" the queue and I get no crashes. If Remove is the first action taken on an active queue, my web GUI cbecomes inaccessible, though it did return once after about 3 minutes.

Considering there's been zero progress here solving the core issue... the Remove Shaper button should be either inactive as long as there's an active queue on the interface, or it should be smart enough to do what's stated in the above comment itself before removing the shaper. This bug is completely unacceptable with remotely managed boxes.

Old report and no recent recurrences. Lots of things in this area have changed, so most likely it's either fixed no longer relevant.
