- On 2026-05-01, a Roblox Developer Forum report said Roblox Studio crashes during Local Playtest in any place file.
- The poster first suspected a "claude" process, then edited on 2026-05-01 to say the crash still happens without reopening it.
- Pattern found: after relaunching Roblox Studio, Playtest #1 can work, but Playtest #2 crashes. A 1.8 MB log file was shared.
- 2026-05-01 report posted: Local Playtest causes Roblox Studio to close/crash.
- 2026-05-01 scope check: It happens in any open place, so it does not look tied to one specific game.
- 2026-05-01 edit added: The original "claude process" guess was corrected by the poster.
- 2026-05-01 evidence shared: `0.719.0.7191339_20260501T052434Z_Studio_E2DDB_last.log` (1.8 MB), which points to Studio build `0.719.0.7191339`.

Developer Context
- This is a Roblox Developer Forum community report, not an official Roblox Corporation patch note, as of 2026-05-01.
- The 2026-05-01 edit is important because it removes a false lead, so people do not waste time on the wrong fix.
- The attached log timestamp (`2026-05-01T05:24:34Z`) gives a concrete crash point that can help reproduction and debugging.
- The thread context is "Welcome & Introductions", so this looks like an early signal that still needs wider confirmation.
- If you build games in Roblox Studio, this can eat your progress fast. Save every 2-3 minutes.
- Your testing speed drops hard when every second run crashes, so bug fixing gets slower.
- Team projects can stall if one builder cannot run quick local checks before publish.
- Smart move for now: test in short loops, save after each loop, and keep fresh logs ready for reports.
- Q: Is this a game script bug or a Roblox Studio bug?
A: Based on the 2026-05-01 post, it looks more like a Roblox Studio-side issue because it happens across different places. - Q: Is the "claude" process confirmed as the cause?
A: No. The poster edited on 2026-05-01 and said the crash still happens without reopening it. - Q: What exact pattern should I test for?
A: Relaunch Roblox Studio, run Local Playtest once, stop, then run Local Playtest again. If the second run crashes, you likely hit the same bug. - Q: What should I include when reporting this?
A: Include exact steps, ISO date/time, Studio version/build, and the newest crash log file name and size. That gives engineers usable data.
- Q: Is there a confirmed fix date yet?
A: No fix date is shown in that thread as of 2026-05-01.
