Mac Excel v16.59 VBA crashes on M1 Apple Silicon

For now, I have to configure Excel to run under Rosetta as a workaround for this problem but I would prefer to run Excel natively. Excel VBA code which runs fine on Mac under Rosetta (or under Windows) displays strange behaviour and then crashes. Variables values are being changed, and this seems to then cause the crash. Any advice? This is using the latest Mac Excel v16.59.
