> I don’t think it’s a power issue as it’s getting 5V1A from a power outlet directly to USB-C into the device.
It's not the total voltage/wattage the PSU can provide, but the voltage at the processor.
The ESP's varying current draw notoriously causes too much noise and a lot of boards don't have large enough decoupling capacitors so the voltage drops too much and it glitches out. Also a warning that USB PSU's can very MASSIVELY in quality (I'd suggest an apple one for testing if you have one handy).
I think you're right that the RISC-V processor is either better behaved and draws power more consistently, or the board has shorter traces to it's bypass capacitor or a larger bypass capacitor.
