BF6 on steam restricted (same EA Account on EA App platform seems fine)

Hello i have a problem with BF6 and my account seems weirdly restricted.

I bought the BF6 on EA App on 1 August, then refunded it later and bought the game again on steam on 17 August.

However, yesterday, 10 October i was unable to connect the game on steam with the following error:

ACCOUNT RESTRICTED

Your EA Account is restricted from accessing online features. Learn why, how to appeal, and more by going to help.ea.com/security-and-rules/.

ERROR CODE 1:86001S:51009S:-17636452900:4128769Q

I made an experiment and re-bought BF6 again yesterday (10 October) on EA App, and there is no such issue with my EA Account.

Please note that i use the same EA Account on both platforms EA App + Steam.

So my account seems restricted only on steam platform, i can play BF6 using EA App.

Because I re-bought BF6 again on EA App after release, i lost preorder bonuses, my preorder on steam has all the preorder bonuses but i cannot play there because of the restriction bug/error.

How can i solve this issue? Who could help me in this matter? I contacted EA advisor via live chat and steam support and still cannot help myself out, they dont know anything about it.
