The buffer is on the above /scp:root@room:/home/study/Movies:

At first line there is folder indented for one space to the
right. Cursor is on that line.

If I press RET on that line I got that error:

dired-get-file-for-visit: File no longer exists; type ‘g’ to update Dired buffer

Typing g does does not help.

Space is at beginning of file, not in the middle of file.

When checking on local file system it works well. When checking on
Tramp scp file system that is where error comes. Other computer is on
GNU Hyperbola/Linux-libre, same as this one.

Debugger entered--Lisp error: (error "File no longer exists; type ‘g’ to update 
Dired bu...")
  signal(error ("File no longer exists; type ‘g’ to update Dired bu..."))
  error("File no longer exists; type `g' to update Dired bu...")
