Unclear how the user might have ended up with a "max" amount receive request in the wallet.
There are several guards against this, such as:

electrum/electrum/wallet.py

Lines 2561 to 2564 in aaca7c5

	def create_request(self, amount_sat: int, message: str, exp_delay: int, address: Optional[str]):
	# for receiving
	amount_sat = amount_sat or 0
	assert isinstance(amount_sat, int), f"{amount_sat!r}"

[SomberNight]

Exporting receive requests, modifying the file, and importing it back, is one way to trigger.
