Not quite understand the current problem you are having, let’s be sure
With dtoverlay=gpio-shutdown
Pressing the momentary switch (wired between Pin 5 and 6) does not initiate a shutdown process but just stops the I2C momentarily.
If you have another device using the I2C, it would be an expected behavior. You need to specify a different GPIO pin to initiate the shutdown.
With dtoverlay=gpio-shutdown,gpio_pin=33
Pressing the momentary switch (wired to GPIO33 and GND) does not initiate a shutdown process.
You might be mixing up bewteen GPIO pins and Physical/Board pins. And only GPIO0 to GPIO27 are lead out to the 40-pin connector. So, GPIO33 is not easily accessible. If you’re meant to connect a momentary switch to the Physical/Board pin 33 (GPIO13), then you should specify it as
dtoverlay=gpio-shutdown,gpio_pin=13
Hints: You can type pinout in a terminal window to display the 40-pin GPIO header's pinout description.
Comments
The dtoverlay statement must NOT contain any space(s).
E.g.
dtoverlay=gpio-shutdown,gpio_pin=33That makes sense, what doesn't make sense is in the picture I provided I had dtoverlay=shutdown and still is now working and messing with the I2C
