Unable to access SWGOH on PC and the Web Store

I am experiencing an issue with my Star Wars: Galaxy of Heroes account.

My account is still fully accessible on my iPhone, and I can play without any issues. In the game settings, EA Connect is shown as "Connected."

However, since August 3rd, I have been unable to access the PC version of SWGOH or the Web Store.

Here is what happens:

The PC version asks me to link my account, as if no SWGOH account is associated with my EA account.
When I click "Yes, Link My Account," I complete the linking process on my phone, but the PC client immediately returns to the same screen and asks me to link my account again.
The Web Store also asks me to link my account, even though it is already linked in the game.
I cannot unlink my EA account from within the game. When I try, I receive the message: "Your account cannot be unlinked."

I have already checked the following:

I am signed in to the correct EA account (the same email address used in the game).
I can log in to the EA website without any issues.
My email address is correct.
I have cleared the EA App cache, signed out and back in, and restarted the game.
The issue appeared without any changes to my account or my PC. I simply shut down my computer for a few hours, and the problem started when I launched the game again.

Before this issue occurred, I regularly used both the PC client and the Web Store, and I have made multiple purchases through the Web Store.

Could you please check whether the EA Connect link for my SWGOH account is still correctly registered on your servers and reset or repair it if necessary?
