It is not possible to put a block into a column

Hello everyone,

It is not possible to put a block into a column
Process: I create a column, I select the column, and i choose the block I want to put inside column, and then I get this kind of message in the system pop-up:

 {"content":" \u003Cdiv class=\u0022tbm-block\u0022 data-type=\u0022block\u0022 data-block=\u0022planet_tototestmegamenu\u0022\u003E\n \u003Cdiv class=\u0022block-inner\u0022\u003E\n \u003Cdiv id=\u0022block-block-content17111dca-6021-4270-8600-512c52cbbcc4\u0022 class=\u0022block block-block-content block-block-content17111dca-6021-4270-8600-512c52cbbcc4\u0022\u003E\n \n \n \u003Cdiv class=\u0022contextual-region layout layout--onecol\u0022\u003E\n \u003Cdiv class=\u0022layout__region layout__region--content\u0022\u003E\n \n \u003Cdiv class=\u0022mx-auto clearfix text-formatted field field--name-body field--type-text-with-summary field--label-hidden field__item\u0022\u003E\u003Cp\u003Etoto\u003C\/p\u003E\u003C\/div\u003E\n \n \u003C\/div\u003E\n \u003C\/div\u003E\n\n\n \u003C\/div\u003E\n\n \u003C\/div\u003E\n \u003C\/div\u003E\n","id":"tbm-column-17"}

But no block is placed in the column.
Any idea?

My conf:
Drupal 11.1.6
tb megamenu 3.0.0-alpha4

php 8.4.5
mysql 8.0.40-31

Thank you in advance.
