I am using a module which gives me this error when I try to open its settings in the admin.
This is part of the stack trace:
app/code/Rokanthemes/SlideBanner/Controller/Adminhtml/Slider/Index.php(70):
Magento\Backend\Model\View\Result\Page->setActiveMenu('Rokanthemes_Sli…')
Code of controller: https://pastebin.com/wVrQ6QcE
I can see that it tries to set the menu for Rokanthemes_Slidebanner which is of course the extension I am talking about. The question is, why it cant set the menu for that single extension while the rest works just fine. I have no idea where to look anymore.
Thanks for helping!

Apparently, it is a bug. Deleting
generated/metadata/global.php
may solve it.
