Ps5 " Request rejected due to your cross platform limitations. " when sending Guild invite.

Trying to add a friend that is on PC to my guild.
I get the following message :

"Request rejected due to your cross platform limitations. "

I also cannot send him party invites.

He CAN send ME party invites however so cross play is sorta working.

I also get this message, so my settings are correct it seems:
"Crossplay with players from outside of playstation network is enabled. "

On a more general note : the game crashes a lot when doing crossplay / guild stuff on ps5.

I have the same problem.

In ps5 options all crossplay settings are enabled to interact with other platforms.

Also, when i write something on chat, PC guild members see my messeges. When they send a messege i dont see theirs messeges on guild chat.

I cant invite them to party, warp to them or vision their hideout cuz of 'cross platform limitations'.

They can warp to me, invite to party etc.

I can trade tho
