Roblox Studio keeps crashing overtime when editing a script

I discovered this issue on Sunday, January 23, 2022, 4:27 PM, Central Standard Time (GMT-6)

In Roblox Studio’s built-in script editor

Expected Behavior:
Display autocomplete without crashing.

Actual Behavior:
Displays autocomplete and works fine for few seconds until it crashes, often without a crash popup.

This has to do with Luau Type checking system (which used to be “Luau-Powered Autocomplete & Language Features” in Beta), though I am unsure what exactly is causing this issue.

Operating System: Windows 11 Pro (64bit)
Studio Version: 0.513.1.5130422 (64bit)

Reproduction Steps:

  1. Open ModuleScript called “TowerGuard”.
  2. Start and keep changing types until Roblox Studio crashes

Workaround: None
Issue Area: Studio, Script editor
Issue Type: Crashing
Impact: High
Frequency: Constantly


We believe that this issue has been fixed.
