Research direction
Start by reproducing the failure at GPIO.add_event_detect on the listed Raspberry Pi 4 system after updating to kernel 6.6.20+rpt-rpi-v8. Compare the edge-detection behavior with the prior kernel and trace the failure reported as "Failed to add edge detection". Done means add_event_detect works again on the stated hardware and kernel configuration.

Description
Describe the bug
Since the update to the following kernel, the "add_event_detect" function from the RPi.GPIO library no longer works.
Linux outdoor enclosurePi 6.6.20+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.20-1+rpt1 (2024-03-07) aarch64 GNU/Linux
The program crashes with the following error.
Traceback (most recent call last):
File "/home/pi/scripts/test/./door_limit_switch_states.py", line 48, in <module>
GPIO.add_event_detect(door_limit_switch_top, GPIO.BOTH, callback=all, bouncetime = 20)
RuntimeError: Failed to add edge detection
I use the following Raspberry
Raspberry Pi 4 Model B Rev 1.5
Steps to reproduce the behaviour
Update to the actual kernel and try the RPi.GPIO library function "add_event_detect"
Device (s)
Raspberry Pi 4 Mod. B
