The problem

I have a strange issue with the reading of files from the SD card:

• Long filenames with extension .gco are listed
• Long filenames with extension .gcode are NOT listed
• If I only change the extension from .gcode to .gco it will be listed
• In terminal "M20 L T" list ALL files with short and long names
  Executing a command dir /X in a command prompt I noticed that the short 8.3 names now contains ~ character also in the extension (MyLongFileName.gcode -> MYLONG~1.GC~)
  This is my guess:
  When long names are enabled, the parsing of the long names is executed correctly from the "M20 L T" command but the filtering for printables files is executed on the 8.3 name. If this is the case then .CG~ files are filtered out as non valid printable files.

Did the issue persist even in safe mode?

Yes, it did persist

If you could not test in safe mode, please state why ("currently printing" is NOT an excuse!)
