Co-op Crashes Game

I am trying to play with a friend, we have the same PCs, we even tried lowering everything to low, resolution to absolute smallest, directx12 or vulkan and nothing worked.

I thought at first it was because it was some issue with his graphics or because our PCs are really old but I wasnt having any issues.

After having him try to connect to my instance multiple times we tried him starting the map and then I join, when he did that he was running around but the moment I joined he crashed even though he had loaded into his own map and was having no issues.

So we tried running the maps solo while in discord, after doing a couple of maps without 0 issues of the game freezing/hanging/crashing I invited him to party to see if Clearfall was maybe the issue, but the moment he tried to join my map again the loading cogs froze and he was hanging/crashed again.

I have brought the game so I can play this league whenever but he hasnt and its so annoying that I cannot even play co-op with my friend during this free weekend, doubt it will be fixed before mid-day sunday.

Sad because last free weekend we had no issues playing, unsure what is even causing this co-op bug as zizaran had 0 issues with him 4 team party earlier today.

Also would like to note that my friend was able to load into clearfall encampment just fine, so being around other entities/players seemed fine, even being in my instance in the encampment was fine...but the moment we left the encampment we ran into issues.

+ Info from playing Sunday, still couldnt play together in a Party ... but also when we joined a party to trade it caused him to crash. Even though we were in the party and able to run around in the same Clearfall Encampment the moment he accepted the trade the game froze, eventually kicking causing to end up offline/kicking from party and eventually would close the game too.

Unsure what could even cause this bug tbh.

May as well also add that for whatever reason he couldnt enter Ogham Manor or whatever its called, crashed a couple times before getting a deadlock detected, I had 0 issues so un sure what error he was having there.

Still couldnt play at any point, did try multiple different times in different locations so ended up just playing together in discord. Unsure if there are any logs that are created that I would need to acquire tho
