Hello, after the most recent Roblox Studio update something weird started happening. Basically when I hit play in studio and then stop I get a gray screen. I’ve tried uninstalling Roblox Studio and reinstalling it but it doesn’t work, I’ve also searched on the Forum to see if people had these issues as well and if there is a fix for it but I couldn’t find anything.
Here is a video to show what is going on.
This happens except in reverse for me, when I play; I get a blank screen. Sometimes, clicking Server/Client helps it. If not that, then re-play. I don’t know why it does it. 
I have this issue too but it’s not as big of an issue as this because every time this occurs I have to restart studio and it happens very frequently…
Since the last update I’m also experiencing issues with flipbooks.
This is the place from Roblox staff from when flipbook was released:
As you can see, the flipbooks aren’t working, just showing the whole image. I’ve got several flipbooks that were working fine until this update. Nearly everyone I try I get an error in the properties to say that the image isn’t the right dimensions (even though they are).
Thank you for reporting this, we’re looking into the issue. For now, we’ve gone ahead and reverted a change that may be causing this issue. Please let us know if you’re still encountering it.
This issue has been around since the new UI update and I’ve seen no fix.
It’s made working on anything Roblox related impossible and honestly I wish there was a way to disable updates, because these new ones do nothing but break studio.
The flipbook issues have been fixed, so at the least, reverting it has solved that issue.
Awesome glad to hear it! I’ll go through and try to fix the actual root cause. Though you shouldn’t be seeing this issue again, if it does reappear, you can just let me know in this thread.
Which issue are you referring to specifically, and with UI update do you mean the Studio update from December of last year?
Hello, I am still encountering this issue and I’ve noticed that if I have 2 games open at the same time in Roblox Studio that it proceeds to break, I hope this is helpful!!!
Huh, thats interesting. I don’t think having 2 instances open at once would contribute to this issue, but I’ll keep it in mind. As for a temporary workaround, I’ve had something similar happen to me on reloading plugins. Closing/opening a plugin tends to get you out of the grey screen and make the viewport come back. I’ve been encountering this issue since the update to the Studio docking system a couple of months back.
Yeah, the one that changed the interfaces icon. It happens when I have more than one studio open at a time resulting in the main viewport to leave my studio into a separate tab.
Sorry to bump, but we’re still having this issue specifically. At random all of our flipbook particles will reset their layout and cause the particles to break. This has been an ongoing issue for months now. This NEEDS to be addressed.
It was fixed a while ago and I’ve not had any problems since.
Just had it happen to us in studio, all of our flipbook particles reverted to the default layout. Spoke to some other developers about it too and they had a similar experience. It happens more rarely now but still happens.
