HELP - Switch stuck at "Missing Boot.dat" SXOS 2.9.4b FW 9.2.0

[nininin]

Hi there,
I had update to FW 9.2.0 quite a while and work perfectly with 2.9.4 beta (Until an hour ago)
I just update ACNH 1.3.0 which it work perfectly fine, then I turn the console off to add some NSP, but I could not boot pass Missing Boot.dat screen.

What I had tried:
> Reformat mSD again
> Use different card
>Just put Boot.dat + Licence.dat

But it still stuck on Missing Boot.dat screen

Please help me with this

Where did you get your nsps from? you know malicious ones have been distributed in the past.

Was you using an emunand partition?

Can you get the main sxos menu up? (Vol up+pwr)

Are you using auto RCM?

How do you inject your payload?
