Extremely slow UT response times on PS5 version

Greetings everyone!

I made a comeback to the game after 2 years. I bought the standard edition recently 'thanks' to the first discount, but I found myself in dissappointment.

First time loading the game and I found it really weird. On the very first loading screen (before pressing any button to access the game) it stayed frozen for like around a minute (thought it was a first time launching screen normal delay), but then when I tried to access the UT mode that issue persisted.

I tried all offline modes and run smooth, but when I connect to UT every loading screen takes a lot of time to respond. I'm seeing the FC green logo more than often and I can't even play a rush game because it always says: "a teammate has disconnected" (yeah, it's me because of the slow loading issue). When trying to play squad battles it takes a lot of time to grant me the reward after thr match. I can't even play rivals because it always disconnects me from lobby.

I tried uninstalling the game, deleting the PS5 cache, rebuilding data base, playing via Wifi, playing via Ethernet and the problem is still there.

I checked some other forums and it seems I'm not the only one facing this issue, but it's not that common.

Does anyone that faced this found a solution?

I'm really dissapointed with this, I'm a fan of UT mode (since 2015) but I never expected such thing to happen. I read that FC25 had a similar issue for some people, but again, I never found a solution.

Please, feel free to share your thoughts.

Thanks in advance!
