Invalid Compact JWE

[shadow talon]

Hi, I'm following this template (https://github.com/vercel/nextjs-planetscale-nextauth-tailwindcss-template), using a mongodb provider, but I'm getting this error all the time when I try to sign in, and even though I can see my account, sessions and stuff in the db, I can see them logged when I active debug: true, but I'm never "signed in", and i'm getting this error..
I really don't know what to do now.
