Hello, The FieldBlock.php block plugin (field_block) from layout_builder, which is used to display entity fields, does not throw a FormAjaxException, so AJAX forms provided from field formatters are not submitted.
Create a formatter that provides an AJAX form, try to submit it, you will get the error: The field "field_name" failed to render with the error of "".
It is also necessary that in the entity_view_display configuration, this field should not be in the content section, since LayoutBuilderEntityViewDisplay::buildMultiple calls the parent EntityViewDisplay::buildMultiple, which duplicates the formatter view call, thereby skipping exceptions before it gets to FieldBlock.php.
Throw a FormAjaxException exception in the same way as you would with an EnforcedResponseException exception.
None.

The change is currently missing an automated test that fails when run with the original code, and succeeds when the bug has been fixed.
I made the error message more descriptive using "Error::logException()". This will be useful because some exceptions do not have a message (as in the case of "FormAjaxException") and their cause is implied in the name of the exception class.
