Board specific options no longer shown

Previously when I clicked on

"Files - Examples"

I was offered the examples for the board attached, in my case for the Uno R4 WiFi or the Nano 33 BLE Sense. Now I only get "Examples from your own Libraries "

How can I restore the examples for my actual boards?

Thanks for reporting it. It's tracked at `File` > `Examples` > `Example for BoardName` and `Sketch` > `Include Library` > `Arduino libraries` menu groups are missing after IDE start · Issue #2239 · arduino/arduino-ide · GitHub. Here is a PR with the fixes: fix: use board+port at startup if it's restored by kittaakos · Pull Request #2242 · arduino/arduino-ide · GitHub. If you want to help with the tester builds, follow the documentation here.

Here is the workaround for now:

Workaround

  1. Select any other board from the Tools > Board menu in Arduino IDE.
  2. Select the target board in Arduino IDE once again.

After doing that, the menus will be populated as expected.
