I didn't check, could be an issue with my addon. Nevertheless the code should check the index before accessing it.
Something like:

 if (isset($database[$name]["table_status"]["Comment"])) {
        $structurecomment = isset($structure["comment"]) ? $structure["comment"] : "";
	if ($database[$name]["table_status"]["Comment"] != $structurecomment) {
             $sql2 = "COMMENT = '".DBA::escape($structurecomment)."'";

Could you check whether your addon does contain comment fields at all? All core tables do have these fields.

My addon does not contains "comments" field:
https://kirgroup.com/projects/fabrixxm/friendica-projects/tree/master/projects.php#L2319

I could add it, but I think a better approach is to be prepared for it to be missing.
either:

• the field is optional, then we check for it and have a default value
• the field is mandatory, then we raise an hard error, so developers know that is missing
