PlayStation Online co-op stopped working.

I created an online co-op game with my cousin yesterday. We played for about 3 hours with no issues, but when we got back on today, it just wasn’t playable. When my cousins tries to join, he gets a console error saying “Something went wrong.” I also get this error after being in the save for a minute or so, then get kicked out. We are both on PS5, both updated to the same version, we have enough cabins, and I am starting the session in co-op.
v1.6.15 build 3
On console so no save data.

Is this what a corrupted save file looks like? The one thing I haven’t tried is changing my NAT type because I’m just not tech savvy enough to want to mess with my home router. Even still, my NAT type is type 2, which wasn’t listed under the more restrictive NAT types and the game worked completely fine yesterday.
