Magento 2.3.5p1 Blank Tab Issue in Configuration Screens
I have a fresh install of Magento 2.3.5p1 running. Passed all requirements for set up, running PHP73 , MySQL 56 and so on and everything looks fine until you go to Stores > Configuration.
Under the General > General Tab, I have a blank area and the same for Sales > Shipping Settings, Sales > Shipping Methods, Sales > Payment Methods, Sales Tax
This is what the screen looks like for reference
I have tried compile, static:content deploy, reindexing, cache flushing and everything else I can think of.
I also have version 2.3.3 running on exactly the same site (using different directories and database of coure) and it runs perfectly, but from v2.3.4 I've had this issue with tabs being blank and cant for the life of me figure it out???? Any ideas? Very grateful for any advice.
