Description

Describe the problem

  • No splashscreen at start
  • Language server fails to start
  • The text in the editor has no colors (probably caused by the language server)

The IDE is otherwise working. Verify, upload and serial monitor works normally.

To reproduce

Place a '#' in the IDE folder name and start the IDE.

Expected behavior

If '#' in the IDE folder name can't be supported in Windows due to limited support in other OS's then a notification to the user should make it clear that the IDE folder name contains an unsupported symbol.

Otherwise since the IDE seems to be running normally except for the language server then maybe it can be fixed to support '#' symbols in windows at least.
