so it works with AO disabled and does not work when AO is enabled? or is the difference more subtle? 🙂
When AO is active then I can not add blocks by clicking below the current block. (AO is the only plugin except Gutenberg which is active.)

As there are a few different issues on the Gutenberg repo I am thinking this has a much higher impact than just when AO is active. As it might have an impact with plugins that add metaboxes in general.
so does disabling the “Enable configuration per post/ page?” option near the bottom of Settings -> Autoptimize -> JS, CSS & HTML “fix” the problem?

Actually does fix the problem!
So this is a metabox issue then. Interesting! I will bring this back to the Gutenberg issue I posted in.
interesting indeed! if there are other plugins with metaboxes that also trigger this bug, then indeed this is likely something to be fixed on gutenberg side.
I just tested with installing and activating Yoast SEO plugin which also adds a metabox to the gutenberg screen. The problem also showed up there. So this is a Gutenberg issue.
I will close this issue and mark it as solved.
seems to be (at least related to) https://github.com/WordPress/gutenberg/issues/63882 ?
