Quick Summary

• On 2026-03-18, a Roblox DevForum report said Roblox Studio play testing could trigger a Roblox Client (Roblox Player) crash-update loop.
• In that report, pressing "Cancel" and closing Roblox Studio did not stop the loop.
• The only confirmed stop was force-ending "Roblox Runtime" in Windows Task Manager.

What's New

1. Observed on 2026-03-18: Clicking Play in Roblox Studio starts repeated client crashes plus update relaunches.
2. Control break: The update "Cancel" button does not end the cycle.
3. Process behavior: Closing Roblox Studio does not end the stuck runtime process.
4. Workaround: Open Task Manager -> find "Roblox Runtime" -> End task.
5. Reported hardware: Ryzen 9900X, RX 9070 XT, 32 GB RAM (so this is not only a low-end PC issue).

Developer Context
Roblox Corporation's Roblox platform gets frequent client updates, and this report looks tied to the handoff between Roblox Studio and Roblox Runtime.
Inference from the source: because "Cancel" and closing Studio both fail, this looks more like a launcher/runtime process bug than a map script bug.
As of 2026-03-18, the thread shows 1 post and 1 participant in "Welcome & Introductions", so there is no linked official fix note yet. Roblox DevForum thread about the crash loop
Why You Should Care
If you build games, this can block testing completely.
If you are a player helping test, you can lose time fast when the loop starts.
Quick player tips:

• Save often (every 5-10 minutes) before play testing.
• Keep Task Manager open during test rounds for fast recovery.
• Write down exact repro steps and PC specs so bug reports are easier to confirm.
• Post technical issues in a bug-report area so Roblox engineers can spot them faster.

FAQ

1. Q: Is this just a random in-game crash?
   A: Not exactly. The 2026-03-18 report describes a repeat update-crash loop during Roblox Studio play testing, not a one-time crash.
2. Q: Does clicking "Cancel" fix it?
   A: In the source report, no. The loop continued after pressing "Cancel".
3. Q: What is the fastest temporary fix right now?
   A: On Windows: Task Manager -> End task on "Roblox Runtime". Then reopen Roblox Studio.
4. Q: Can this happen on strong PCs too?
   A: Yes. The reported machine on 2026-03-18 used Ryzen 9900X, RX 9070 XT, and 32 GB RAM.
5. Q: Is there an official Roblox patch note for this bug yet?
   A: None is linked in the source thread as of 2026-03-18.
