All playtesting options get bricked when you end a multiplayer session that was initiated with ExecuteWithStudioRun. I’ve been able to reproduce this in a baseplate place, so no file to attach.

MacOS Sonoma 15.6.1
Roblox Studio 0.695.1.6950959 (arm64), channel production (latest)

Steps to reproduce:

  1. In any place file, Insert TestService (if it isn’t already present)
  2. In TestService, set the following properties:
  1. From the playtest dropdown, select Run and press the Play icon button

  2. Wait for the server and client sessions to fully load
  3. On either the client or server, select End session

  4. Attempt to start any playtesting session (i.e a regular Test playtest session)

  5. Observe

You are now unable to start another playtest session (not even Run) until you restart Studio.

Expected behavior

I should be able to start the next playtest session, without having to restart Studio
