      Hello,

      I upgraded from Moodle 3.10 to 4.0.1+

      I got errors in the website-adminstration:

      Undefined property: stdClass::$enableaccessibilitytools in D:\Inetpub\....\blocks\accessreview\block_accessreview.php on line 176

      generalexceptionmessage
      		 
      Exception - Return value of block_accessreview::can_block_be_added() must be of the type bool, null returned

      The plugin "accessibilitytools" was not enabled automatically during the upgrade.

      Solution:

      I could solve the problem by activating accessibilitytools at website-administration --> advanced features --> activated the checkbox for accessibilitytools

      Afterwards the problem was solved but it took quite a while to figure out the cause.

      Environment:

      OS: Windows 2016 + IIS + PHP 7,4,29 (64 Bit)

      Desired behaviour:

      The extension should be activated automatically during upgrade or moodle should run with deactivated accessibilitytools.
