Joined a game today, it updated my roblox version.
Now when I try to view the explorer window in studio it just goes blank.
Closing and opening explorer doesnt help, I have to close and open the file again.
This happens after I’v pressed play in studio and then pressed the red stop button.
Then this white screen is all I see.
Yeah I get this - I usually have to click an open script tab and then back to the main game and then it appears. If I don’t have any open tabs, I have to close the file and open it again 
This happened to me this morning when I was testing my game. Quickly fixed by turning it off and on again.
This happens randomly, and Roblox is aware of the issue. The problem is that there’s no clear repro for the bug.
A fix for this will be in next week’s update. Let me know if it’s still happening after that is released.
Been waiting for this since August. Thank you Silent-san!
A bit late but I was able to reproduce this by opening client-side things (i.e. my Camera) - Only if I open my camera and browse the children I put into it will the explorer disappear.
There was an issue with the fix that caused Studio to crash, so its been delayed another week. Sorry everyone
