Comment:

 Further testing:

 I created a custom block theme and a custom child block theme.
 Results: Site Editor loads as expected. ✅

 I switched the `Template:` header for `Twenty Twenty-Two (Swiss)` over to
 the custom block theme.
 Results: Site Editor loads as expected. ✅

 I installed `TT1 Blocks` and switched the `Template:` header for `Twenty
 Twenty-Two (Swiss)` over to `tt1-blocks`.
 Results: Site Editor loads as expected. ✅

 Confirmed: The issue only seems to occur with Twenty Twenty-Two child
 themes.
