[Bug] Keychron K8 RGB ISO crash/lock-up

[deadproprietary]

Describe the Bug

My Keychron K8 RGB ISO locks up permanently after typing for a random amount of keystrokes and becomes unresponsive. It does not seem to be caused by the amount of keys pressed at once. During the lockup, the keyboard may send input of the last pressed key as if it were held, and random RGB backlights may flicker very rapidly.
Re-plugging the keyboard either through USB or the switch resets it.

Additional Context

I have tested this both off the sn32_master and sn32_develop branches. Both exhibit the same issue.

old ARM GCC versions prior to 10.3 stable were prone to introducing this. Please test with the latest gcc-arm-none-eabi
