[BUG] Serial printing gcode file fails to extrude beyond first layer perimeter
Printer model
MK4
Firmware version
6.0.4
Upgrades and modifications
None
Printing from...
USB Cable/Octoprint
Describe the bug
When printing via USB connection the printer completes the brim if selected and first layer perimeter, but when moving to the first layer solid infill unloads the filaament and does no further extrusions for at least the next five layers (at which point i canceled the print)
Loading the same gcode file (linked below) to a usb stick and printing directly from the printer resulted in a successful print.
Issue appears to happen no matter what gcode file i attempt to print via octoprint, restarting the printer does not lead to a change in behavior. First observed with firmware 6.0.3, remains in firmware 6.0.4
How to reproduce
Print a gcode file via usb cable/octoprint. Behavior should occur
Expected behavior
Printer should not retract filament after first layer perimeters with serial printing and should perform a successful print like it would with the same gcode file loaded to usb.

gcode prints successfully via USB drive, fails via octoprint/usb cable printing
