ERROR: Language client is not ready yet

Software IDE 2.x
1

A previous working setup with the IDE 2.2.1 now suddenly refuses to compile anything, not even the simplest "Blink"-example.

Error message in the IDE is "Compilation error: exit status 1".

Looking in the terminal window where I launched the IDE (with sudo) I see the following:

root ERROR Unexpected error when firing event on build did complete. "file:///private/tmp/arduino/sketches/7D5EF730081766D5D5CB148A0BD1036F" Error: Language client is not ready yet

Running the IDE on Mac (M1) with MacOS 14.1.2

I've restarted and also reinstalled the IDE but problem remains.

Thanks in advance!

/S.

UPDATE: Went back to IDE 1.8.19 with the exact same wiring and sketch and then everything worked flawlessly. Will probably stick with 1.x.x until 2.x.x works better.
