Weird Steam glitch?

Hey everyone,

Looking for some insight on a strange Steam bug I just experienced.

While playing Scrap Mechanic, Steam suddenly crashed and closed. When I reopened it, the "Play" button for Counter-Strike 2 had changed to "Connect," and Steam listed CS2 as currently running even though I haven't opened or played it in months. I did not click Connect.

After completely closing and restarting Steam, the issue went away and CS2 was no longer listed as running. However, the "Last Played" date for CS2 updated to today.

I immediately checked my account security:

Only my PC and phone are authorized/logged in. Steam Guard is active. No suspicious login history or unrecognized devices.

Given that it happened immediately after a crash, my guess is that Steam entered a buggy state and misreported an active session, rather than an actual account breach. Has anyone else seen Steam misreport a game as running or update the "Last Played" date after a client crash?

It must be a glitch right?
