Error saving posts with old blocks

Hello! I’m having issues with PublishPress Blocks when saving posts or pages. If I make changes to the content, I get the following error in the console from /wp-json/wp/v2/pages/post_id?_locale=user :

{
"code": "rest_cannot_update",
"message": "Sorry, you are not allowed to edit the advgb_blocks_editor_width custom field.",
"data": {
"key": "advgb_blocks_columns_visual_guide",
"status": 403
},
"additional_data": [
{
"key": "advgb_blocks_editor_width",
"status": 403
}
],
"additional_errors": [
{
"code": "rest_cannot_update",
"message": "Sorry, you are not allowed to edit the advgb_blocks_columns_visual_guide custom field.",
"data": {
"key": "advgb_blocks_columns_visual_guide",
"status": 403
},
"additional_data": [
{
"key": "advgb_blocks_editor_width",
"status": 403
}
]
}
]
}

I’m unable to update the content of the posts on the page. Everything is updated, and if I deactivate the plugin, it works fine. I assume the problem is with PublishPress old blocks or configurations that are no longer compatible with the latest version.

Greetings
