Upload to SD issue - FlashForge

What is the problem?

After Flashforge Finder 2.8.4 update, it seems the M104 command gets ignored and swapped with a default temperature of 180 degrees.
The problem only appears when I send the gcode via CURA or upload through OctoPI "Upload to SD" command.

NOTE: the previous behaviour for this specific printer was to get up to 180 degrees, and then increase again to the defined printing temperature. This last step now is skipped and it starts printing at 180.

If I stick a USB key with the same file into the USB printer port, it works correctly.

What did you already try to solve it?

Yes, done different tests and run debug serial mode. I can see the printing temperature set to 180 even if the gcode shows M104 S230 T0:

Have you tried running in safe mode?

No, flashforge need an external plugin to work. However, I uninstalled all the other plugins.

Did running in safe mode solve the problem?
