More players in a challenge than in the party, causing game error. 305594340

Just playing Skate. and starting a co-op challenge, when the challenge starts it says that there are 3 people in the challenge when there is only 2 in the party. I have also seen it go all the way up to 5 players at some point as well. But thats only a part of the issue, if the random players that ended up in the same challange completes it you get all the rewards from it. But if at least 1 of the random people that ended up in the challenge leaves, when you complete it you get an error. You then get 0 rewards and need to do it once again just for the same thing to happen all over.

I am playing the game from steam. I did co-op challenges for about 1 hour 30, at around 18:50 CET (29/9/25). Then went afk and got kicked for inactivity. came back at around 19:30 to play some more and do the new daily challenges. after that all this started happening at every co-op challenge i started. At this current state its about a 90% chance that there is random people in the same co-op challenge that i start.

I did have my party turn off cross-play, but it doesnt seem to make that much of a difference from how much this is happening.

2 players in the party, 3 players in the challenge.

Error after the random person leaves the challenge and my party completes it.
