Fix Roblox Studio Randomly Locally testing the game?

Hello, sorry for being inactive on this site for so long.

So when I use Roblox Studio, sometimes it will just add more roblox studio tabs running the game randomly. It opens as much tabs as it can until my computer crashes and i need to hard reset it. I even set my local server test count to 2 and it opened more than 8.

It annoys me so much, and i really need help.

Please help me
