Panda Touch not displaying thumbnails for .3mf and .gcode files

My Panda Touch is consistently failing to display thumbnails for both .3mf and .gcode files. Instead of a preview, I see only blank squares in the file browser and a generic panda icon when a print is active.

### **Details:**
- All files were created using Bambu Studio
- Printer model: P1S
- Firmware version: P1S firmware - 01.07.00.00
- Panda Touch firmware versions tested:
- 1.0.7
- 1.0.6.3
- Thumbnail settings: Tried with Enhanced Thumbnails both on and off
- Thumbnail locations checked:
- Cache folder
- Root folder
- Active print preview
- No thumbnails appear in any context.

### **Troubleshooting steps taken:**
- Reflashed/rebooted the Panda Touch
- Searched for known issues — this has been mentioned by many other users in past firmware threads
- Tried multiple firmware versions without any change in behavior

### **Expected Behavior:**
Thumbnails for .3mf and .gcode files should display correctly in the Panda Touch interface when the files are prepared using Bambu Studio and transferred via SD card or network.

### **Actual Behavior:**
No thumbnails are displayed. Files appear as empty boxes in the browser and as a panda icon when printing.

### **Additional Notes:**
From user reports and community feedback, it seems this issue has persisted for several firmware updates without resolution. If this is a known issue, could the team please confirm whether a fix is in the works?

No source file, test, or entry point is identified in the report. Reproduce the missing thumbnails on a P1S using Bambu Studio .3mf and .gcode files with the listed firmware versions, then trace the Panda Touch thumbnail handling; done means previews appear in the file browser and during an active print.
