Roblox's Mutex breaks sometimes, causes unnecessary log spam and allows multiple Windows of Roblox to be opened at all times

Roblox’s Mutex now allows for multiple Windows to be opened on my machine due to a issue with the checker. I can open as many as I want with no issues showing up.
This has started happening for me around 658 / 659 and ever since.

It is not 100% of the time that it happens, but MOST of the time.
This seems to be happening when you open Roblox too fast from lets say, a desktop shortcut. It doesn’t catch up the first time and remains like this until Windows restarts.
Although, I have managed to experience this in other times as well, on just normal playing of Roblox. I have no idea how to reproduce it from that point as it is very random.

Expected behavior

  • I would expect Roblox to automatically close upon the opening of multiple tab
  • I would expect there to be no spam on logs due to a failing check, which adds up and wastes a lot of space without clearing logs from time to time
