   • or 9.2.7, or 10.0.0-alpha.6

   • The connection seems to succeed (no error message),
   • No files are listed on the board,
   • Attempting to upload a file shows the loading animation (the snake) indefinitely, but the upload never completes.

Description

No response

Additional information

I also tested File Glider: the board appears, but selecting it throws an error.

Web Serial works correctly with the board.

Unfortunately, I don’t have an nRF52840 board to compare against.
