Account doesn’t have early access?

Hey guys, so when the early access started I bought the founders pack to get access and play the game on my ps5.

Now I thought I give the game another try, this time on pc. I’ve read there is cross progression so my bags etc I’ve bought are still there. Downloaded the game on pc and tried to log on. Getting the error stating that my account doesn’t have early access.

Can’t I use my ps5 account to continue playing on pc? I could log in at the offices homepage, linked an email etc.

Does anyone have a solution for this or do I have to buy the 30€ pack again?

Thanks for your help
