Context: Switch1 is the problem. Switch2 is the newly hacked switch.
Okay so I tried making a new user on switch1 and that didn't work.
I then tried it on switch2 that I just hacked, and used linkleho on.
It worked.
I deduced that it was something wrong with my atmosphere folder on switch1 so I deleted that and reinstalled atmosphere.
it worked.
So if you're having issues with ACNH not loading on 2.0 Delete atmopshere (Don't forget to backup mods and stuff) and reinstall the latest atmosphere and run. If it works put your contents folder backup back in and check if it still runs. In my case it doesn't and I'm trying to figure out why,
I'm also high af rn.
