Likely this is an issue that would need to be resolved through PlayStation Support, as the error code can be triggered by hardware failure.
As you are attempting to add hardware (the keyboards) to your PS5, which then causes the crashes, I would suspect the PS5 doesn't like the keyboards or doesn't have 100% compatibility with them at a hardware or software level.
