UM problems from 2.6.2 to 2.6.7

From the version 2.6.2 to 2.6.7 my website do not display profiles and account.
I have skipped 2.6.1 so I don’t know about that version.

The blocks in block editor show invalid content notice, if i try to recover a block, it says block rendered empty.
Yesterday I managed to get profiles and account in 2.6.7 with shortcodes in classic editor, before that i cleared the pages, and purged cache. The profiles are now distorted and stretched, with half of the profile covering the footer widgets. So you can see lines and text over the footer widgets.
With 2.6.0 UM blocks still behave normally.

I have done some tests on a fresh installation of wordpress: on a subdomain, in a subfolder. I started with the theme 2023. After UM generated its pages, version 2.6.7, I made one short profile in UM forms. I can see my own profile, and my account. If I go behind into editor, I see classic block with shortcode. If I look for UM blocks, there are none, they do not exist. The profile does not let me add any text in the profile description.

Then I tried with 2.6.0, again the same thing, there are no UM blocks. This version lets me add the text into description. I downloaded classic editor too, and tried with the GeneratePress theme, with the same results.
