Unable to start or stop a play session

The AI assistant is unable to start or stop a play session. The issue began today and occurs with both Claude and the Roblox AI assistant. I tried it on both Mac and Windows, and it doesn’t work anywhere.

Can confirm this is repro-ing for me too - the start_stop_play MCP cmd is broken.
But manual F5 and StudioTestService still works.

Hey, this should now be fixed. You may need to restart Studio. Thanks!

its working! thx for your work

Hey! I’m getting infinite hanging when attempting to Start/Stop via MCP on the latest Studio Ver.

What info do I need to send the team?

Hey, can you restart Studio 1-2 times and try again? A bad rollout caused the bug to resurface yesterday, but we believe it is fixed again.
