Hello @megaisabela, i was able to verify on my device but it is more like a cosmetics issue because when any music is being clicked on for possible changing of the file name the error pops up but the music will eventually get renamed,
after proper check, the error do pops up majorly when music on SD card are being renamed but the action will still get processed anyway.

I attached a video to show the behavior properly on my device
