Compatibility issues with WP 6.2 beta1

I just started testing WP 6.2 beta1. Right away:

1. The ACF Blocks in Edit mode are broken, the Preview mode is ok.

2. This is not new, but I don't think anyone has mentioned it before, the same thing as issue 1 happens with the Site Editor, with 2 distinctions: The first one is that the Edit mode button never shows up, BUT, in the inspector (right sidebar), the columns set in the Field group do not break into a single column, which makes things very difficult. My so far solution was to configure my ACF Blocks in a temp. page, and then simply copy them to the Site Editor.

3. Side note: This is not related to ACF PRO, but I'm finding that many other plugins and themes are getting broken with just 10 minutes of testing: The Wayfinder plugin no longer works, as a backup I had the Block Guide Lines to use from the EditorsKit plugin, both of these solutions no longer work, so I'm left with the white space to guess where to click to select an element, of course we have the breadcrumbs and the block Navigation menus. Also there are things that are breaking my FSE theme, like I no longer have a Sticky header, instead I have some extra paddings. Disabling the Sticky header option the extra padding seem under control, but I have to come up with a new sticky header solution. The bottom line for the 3rd point is that test all your plugins and themes that you use...

Start by reproducing the reported behavior with WordPress 6.2 beta1, checking ACF Blocks in Edit and Preview modes and then in the Site Editor. Separate ACF behavior from the unrelated plugin and theme problems described in the side note. Done should include a confirmed fix for the ACF block editing and Site Editor layout issues, with regression coverage if the repository provides a relevant test entry point.
