  • Does it happen with factory settings?
  • Does opening new windows in general work, like for preference or View > Area > Duplicate Area into New Window?
  • Does opening the file browsers in as en editor in the main window work (e.g. in the Shading workspace)?
  • When running Blender from the terminal, it will normally print a backtrace or output a crash log. Please attach that here.
