I am having the same problem with OP.
I don't have any random issue on my 2 switch consoles at all.
I just purchased another switch console 2 days ago and I failed to send any payload to it.
Using the same PC with my other 2 consoles, both of them works fine but not this newly purchase switch.
I know exactly what I am doing, I can boot up another 2 older consoles just fine.
Can you check on the back of your nintendo switch for year and model ?
Mine are:
2018 HAC-S-JXE-C3 = does not work
2016 HAC-S-JP/EU-C0 = works fine
2017 HAC-S-JP/EU-C1 = works fine
Thanks.
YES i have the "HAC-S-JXE-C3"
Okey i will sell it when i will come back to my country and try to get a second hand one
