Unable to connect (Minecraft PS5 Bedrock Edition)

I'm on PS5 Minecraft Bedrock Edition and I keep getting the Unable to connect error for 4 months now even though I have PlayStation Plus, I tried lots of things but I still couldn't fix it, it's unfair that I have PlayStation plus and still can't play with my friends. I can join big servers but I can't join my friends world from the (Unable to connect) error, another thing is that I can join my friends world on the old Minecraft PS4 Edition but can't join a world in the bedrock edition
