Additional context

Add any other context about the problem here.

.gcode File shows a kind of pragma [[totalSlices]] that causes strong typed uint32 property to fail. Supposed to be Manifest.xml slice count.
Cannot assure if it's a needed parameter, so maybe bypassing exception (casting to 0) should be enough to load the file and do standard operations. (Event doing with each of the properties failing casting and just pop an warning or log could be helpy)

I based the gcode parser on CWX. It seen diferent slicers use diferent gcode for the printer, god damit... Also number of slices = number of layers, no sense redundancy
I will fix that on next release.

My big advice here is use PrusaSlicer instead and convert to your printer... even when i fix that, UVtools will have missing data with the information your slicer is outputing.

EDIT:
I see that gcode is also malformed:

;********** Pre-Slice 330 ********
G4 P0 ; Make sure any previous relative moves are complete
;********** Layer 330 ******
; 0
; 330
M106 S255 ; UV on
; 0
M106 S0 ; UV off
; Blank
; 0;********** Lift Sequence 330 ******
G1 Z0 F0
; 0
G4 P0 ; Wait for lift rise to complete
; 0
G1 Z0.05 F0
; 0

Why every delay and lift is 0 @ 0 speed?

Seems got WCW misconfigured, sorry. Here´s a proper file.

Will try, thanks!

Really printer vendors should adhere an standard 🙄
Luckily, We've got UVTOOLS 😄

I just confirmed, things like resolution, layer height and other informations required by uvtools are missing on that slicer format. Is possible to get them via calculations but i think not worth to have all that extra conditions for such format. CWX otherwise is full compatible.
You can setup a new printer on prusaslicer and work from there
