Hello my dear friend @achim03, running out of ideas or getting blocked is something very common in writers, possibly sometimes because of a little mental exhaustion, which can easily be solved with some recreation as you mention, in my case when that happens to me, I also turn off the computer and take paper and pencil, I think that writing and erasing relaxed me a little, and so the ideas come little by little, it is more work because then I have to transcribe everything, but it particularly works for me.

See you later, thanks for sharing your experience with us, have a great weekend !
