Uninstall issue

Full nonsense. Installed and the site immediately crashed. Trying to uninstall it also crashes the site.
I had to rebuild what it wanted in the DB to be able to uninstall this module.

I had to add a column:
ALTER TABLE `menu_link_content_data` ADD `menu_item_override_children` INT NOT NULL AFTER `revision_translation_affected`;

and create 2 tables with blank columnts which are attached here

This one https://www.drupal.org/project/menu_items_visibility → did the job for me.

I've just tested this on a blank install of Drupal 8 and I also cannot replicate this. Whether it was a particular issue with Drupal 8 at the time and a misconfiguration between core's "Menu Link Content" and the 1.x-dev version of Menu Item Role Access is difficult to replicate and I cannot find any specific versions of core or this module mentioned in the comment thread.

In any case, as Drupal 8 is end of life now and the 1.x-dev version requires it...:
"drupal/core": "^8"
The 2.x version is released now and is the recommended version. I'd imagine if nobody is getting this issue any more (as we've had no activity for 11 months now), we can safely close this issue as "Cannot reproduce", unless we get more information and then another issue can be created.

I just installed on Drupal 10.3.10 and it won't uninstall. Luckily I took a db dump before installing so I have to roll back the site.
