Unable to create new product in Admin or view Pages 2.3.5-p1
I just installed Magento 2.3.5-p1 with Sampledata and everything seems fine until I go to admin panel and view products page or category or pages etc. I get a blank page and errors in the log files. I am also unable to add new product and I see nothing but a blank as shown in the screenshots.
