Sovol SV06+

How to reproduce

1. go into my printer settings
2. go to Machine G-Code
3. click the detailed editor view
4. search for something cursed like "line_width" in the placeholders list
5. click "save" or "cancel"

Actual results

Any edits are lost.

Expected results

Should crash, and potential evaluation errors (i.e., type errors, missing vector references, etc) should be highlighted in the editor before you hit save.

The contents of the editor should not be lost.

Anything else?

I thought this was due to the crazy machine start GCode I was entering, basically I wanted to make the initial lines for priming use the same speed and flow rate as the initial layer and retract and stuff, and I could use placeholders to sort of do this (although, can't quite do all the math without functions like sqrt). Really I just want to draw a line at the standard initial layer wall width, then move over the same width and draw a line back the other way. I thought the bug depended on having crazy GCode in the editor, but it seems even with the pictured GCode, more or less standard, I could get it to crash just by searching for certain placeholder names and then exiting the dialog (cancel or save, doesn't make a difference).

I get quite a few crashes from my system, getting all the GLX stuff to work can be a bit of a nightmare, but this one doesn't seem to be that and seems very reproducible.
