I can’t get the 4500 irishards reward

PS5

I’m writing to you because I can’t get the 4500 irishards reward. When I tried to link my PlayStation account to my behaviour account I got this message :

“You cannot link a PlayStation™ account different from the previous one.”

I never tried to link my PlayStation account to my behaviour account, I checked if I had a linked account and I don’t, so why it doesn’t work ?

ps: if one day I get a PC and I want to transfer my progression from PS5 to PC, I will not be allowed to do it??

Please help me to fix this issue, thank you
