Hacking Question Pokemon let's go error 2618-0006 (AMS)

[LoneFlo]

Hello there !
Local trade suddenly stopped working with Pokémon let's go Pikachu, I always get the 2618-0006 error code. I'm currently on 7.0.1 ams 0.8.9, but I also tried to update to 8.0.1 and downgrade to 6.2, but it didn't work.

If anyone knows this problem...

Works perfectly with ReiNX, so this is an Atmosphere's problem.
