No page loads, just "Internal Server Error"

Since this morning, anytime I try to visit anything anywhere in these forums normally, I only get a blank page with "Internal Server Error." (It worked fine yesterday, which is the first day I accessed the new forums.)

Searching for the problem turns up at least one other person with the problem (thread 1, thread 2), and it seemed to happen when they had some kind of anti-tracking protection enabled. For me, I don't use AVG, but it seems to be related to some extension I have installed, since I can open these pages in an Incognito window (where most extensions are disabled). However, it's not AdBlock or Ghostery, since the forums still won't load with them disabled, and no other extension should be related in any way. I have Do Not Track enabled in Chrome, but that should apply regardless.

This is absolutely egregious.  There should be nothing I can do on my end that causes EA's site to throw a server error like this. And it certainly shouldn't still be happening months after it was first reported.

The issue is happening for me in Chrome v130.0.6723.92 on Windows 11. (No issues on my phone in Chrome for Android v130.0.6723.74 on Android 13.)

UPDATE: It's not an extension but something Chrome must otherwise be handling differently between regular and Incognito windows. I fully disabled every single extension from the extension management settings, and still all EA Forums pages only load as "Internal Server Error" in non-Incognito windows.
