Bug Description

When I start a print using the virtual printer in proxy mode and auto-archiving set to "on", the corresponding archive entry is created, but incomplete / broken:

The print is forwarded perfectly fine to the real printer and prints as expected, but it seems that bambuddy is unable to store / analyse the gcode and so is unable to extract a thumbnail / filaments / time etc.:

Also, when trying to upload the corresponding source-3MF to this "broken" archive entry, the UI says HTTP 500 and fails to do so. Additionally, after printing, the blue icon for the finish photo becomes visible, but when I click on it, it doesn't load (displays a full screen broken image symbol instead).

Expected Behavior

I expect the archive entries, which are automatically being created when using VP in proxy mode, to contain all the infos as they do when I directly upload to Bambuddy (Print on Printer Card / Bambuddys File Manger etc.) - this works fine as you can see her:

Steps to Reproduce

Steps to reproduce == Actions recorded in my Log file:

Sync Printer Settings in Bambu Studio with VP in Proxy Mode (Works as expected)
Hit "Print" in Bambu Studio to start printing on the VP in Proxy Mode
Wait some time until the Archive entry pops up in Bambuddy (FAILS: It does show up - but without thumbnail, estimaed time etc.)
Extra Step: Trying to Assign Source 3MF file to the new Archive

Note: My log contains an unrelated AMS/Printer error (forgot to connect an PTFE tube, sorry).

Damn ... you are right ... I owe you a beer, I guess 🙈😉

Now I only have to find out how this (well-hidden) check-box got unchecked, because I remember ticking it right after installing bambuddy many versions ago, but not to uncheck it afterweards 🙈

Thanks a lot!!!
