SWTOR is not working on Steam at all

Hi everyone,

I have been struggling with launching the game on Steam for almost a year now.

Whenever I try playing, the green Play button switches to the blue Stop button, then back to the green one without anything.

No error message, no login window, nothing.

I checked the firewall - ok.

I did the game file integrity check - nothing

I checked if the launcher is having the Launch as Administrator set - yes. And when I try to launch the game from that, it says that it's already running (Task manager says otherwise).

I reinstalled the game - multiple times

It works with the regular client, but very annoying that I could use the Steam version before, and for no apparent reason, now I cannot.

Started after switching to Win 11, I believe maybe that's the case, but I know people who can run it no problem with Win 11.

There was a link in the forums that people considered the best solution. Of course the site has no longer been available (why would it be...? I need it now...).

Is there anyone with a similar issue? Or someone who had the same but found a solution other than reinstalling the entire OS?

I went through this forum, the SWTOR forum, the Steam forum... nothing...
