Magento2.3.5 Di Compile Breaks custom module admin grid

Question

I have an issue whether in developer or production when I run php bin/magento setup:di:compile

I get Fatal error: Uncaught Error: Call to a member function setActive() on bool in /var/www/vhosts/dev.test.com/htdocs/vendor/magento/module-backend/Model/View/Result/Page.php:27 Stack trace: #0 When code $resultPage->setActiveMenu('Vendor_Module::entity'); then I get a blank page 200 ok There is nothing in exception.log

If I run php bin/magento setup:upgrade after di:compile then * is ok and the grid displays.

Any ideas.

I've found out that the problem was in my controller name index.php it and once I fixed everything worked ok so My file had to be Index.php instead
