Trying to open studio causes it to crash and give this error. I was using studio yesterday, so this is a new bug today.
Someone else in chat is also experiencing this issue.
Expected behavior
Hopefully fixing whatever this bug is so we can open studio.
We are aware of the issue and are actively looking into it!
At the moment, please do not try to uninstall and re-install, as it does not mitigate the issue. We have confirmed that this issue does not resolve with reinstalling. The error also pops up when you try to uninstall from control panel 
Adding to it - this error always appears whenever Studio is starting up.
So no matter if I start it up as an admin or even try to uninstall Roblox Studio, this error appears and closes Studio.
got the same error roblox studio is down
Thanks for taking care of this!
Currently also experiencing this, it’s time to play the waiting game til it gets fixed.
I was finally able to launch the installer and Roblox!
This should have been resolved last Thursday-- please let me know if it happens again!
