 GameMaker Studio 2 doesn't open ! [ Unable to login - failed to get a Steam session ticket ]

I bought GameMaker Studio 2 on Steam. but I couldn't use it so much since I bought it. I always get the same error. I rarely see this error when I'm lucky. But I usually see this error.

When I try to open GameMaker Studio 2, these events are happening respectively.
• A window that says : "Error (42) - One or more required parameters was missing" I click the only button that is "Retry".
• GameMaker wants me to enter my email/username and password
• Then a window comes that says this : "Unable to login - Failed to get a Steam session ticket."
If I click the Retry button that is only button, the window is coming that asks username and password again. And a vicious circle begins.

I tried reinstalling GameMaker from Steam for a lot of times. I also tried switching between different beta versions. But in all, the result is the same.

I also experience a different problem when I try to install the standalone version. The installer wizard tells me that GameMaker is already installed on my computer and will be uninstalled (Even if I had previously uninstall Game Maker using Steam.). I choose OK, so the old GameMaker will be deleted automatically. However, after clicking OK, the window disappears and the wizard never comes back. If I open the wizard myself again, I still get a window saying that GameMaker is already on my computer. And a vicious circle again !

I really don't know what I should do. All I know is that I bought GameMaker, but I haven't been able to use it for a long time. :( Please help me...
Thanks...
