Errors on multi-store admin product page

[PoorlyRabbit]

When using ADM_QuckDevBar in a multi-store environment an error is shown in admin if looking at a product in a store view.

The error is generic in nature, I disabled the module and the problem went away. So no log file of the error or other help. Thought you might want to know though.

What kind of generic error did you had? javascript, php ?
Can you give me a screenshot of the error?

Not OP but might have similar issue. I am experiencing this message in admin panel in any page

A technical problem with the server created an error. Try again to continue what you were doing. If the problem persists, try again later.

In logs there is this error:

Request validation failed for action "Magento\Backend\Controller\Adminhtml\Index\Index\Interceptor" {"exception":"[object] (Magento\\Framework\\App\\Request\\InvalidRequestException(code: 0): Invalid request received at /var/www/magento/public/vendor/magento/module-backend/App/Request/BackendValidator.php:176)"}

This was after creating another store and store view, changing base URL for new store, and changing what store to run in nginx server config.
