Can you send some screenshots and/or a video clip of the issue you're facing? I tried messing around on the linked project, but I can't seem to trigger any parser errors.

Also I've tested with v4.1.1-stable, please check if this has been fixed with this latest release.

I updated to 4.1.1-stable and still saw the issue.

Thanks, I've managed to replicate the issue. I'll detail it here for someone else to tackle since GDScript stuff is not my "forte" 😉

On the following code:

enum MyEnum {
	VALUE1,
	VALUE2,
}

func some_func() -> int:
	var some_var = randi_range(1, 6)
	
	match some_var:

• On a match value, writing "" instead of : triggers a modules/gdscript/gdscript_parser.cpp:4337 - Parser bug: Mismatch in extents tracking stack. error:

Peek.2023-08-08.15-39.mp4

• Code completion on a return value of an enum triggers Parser bug (please report): Trying to check compatibility of unset value type error. If the function's return type is omitted, the error no longer occurs:

I have the same problem (Trying to check compatibility of unset value type) on Godot v4.1.1.stable - Windows 10.0.19045.3324 - Compatibility renderer - NVIDIA GeForce 9400 GT - 8 GB RAM - Intel(R) Pentium(R) CPU G4400 3.30GHz

Same/similar issue on 4.1.2.stable.mono as well, with the following code:

func example() -> Vector2:
    return Vector2.ZERO

When adding a . to the end, or removing .ZERO and trying to type it back, the "Parser bug (please report)" occurs

• Fixed by GDScript: Properly track extents of constants #79301.

• Code completion on a return value of an enum triggers
