Can't Play Shared Dynasty After Update (PS5)

My friend & I had a shared dynasty that we had running for 3 seasons already, both on PS5. However, after this most recent update, everytime I try to login to our shared dynasty, I get the error that "the requested league is temporarily unavailable." I am able to log in to my other online dynasties, so it seems local to this specific dynasty. Is there any solution to this? Would hate to lose 3 seasons worth of progress considering it's not just on my end.
