It was working at first, but stopped yesterday.
Windows 10 Home 22H2.
Rebooting doesn't help.
These screens alternate - then there are just no boards, then nothing at all.

While the IDE is displaying messages in the right bottom about "updating index ...", it will not know about the boards and hence can't show them. There is a known bug that will result in that process hanging till serial plotter (if open) and serial monitor (if open) are closed (in that sequence, close plotter first, next monitor).
Can you select a board and port using the tools menu while the IDE is in the non-functional state?
Now everything works and does not depend on the monitor opening.
Through the menu the selection worked even when the window was frozen.
The failure is not stable, it is there or not.
I completely rebooted both arduino and windows that is all hangs should be reset. And I did not turn on the monitor and plotter. But it didn't help.
Before the crash I installed new libraries, maybe it had some effect.
Yes the glitch came back after installing the libraries.
The monitor and plotter are disabled.
Logs might shine some light on it. See Cannot get ide2.3.3 to start up - #3 by ptillisch and post the results here.
Alternatively, install IDE 2.3.2. You can download from Release 2.3.2 · arduino/arduino-ide · GitHub. Expand assets and select the desired approach (exe, msi, zip).
Once installed and it offers to upgrade, click "Skip version" so you will not end up with 2.3.3 again.
