Upgrade to 5.3 - can't see js file list or search js files now

After upgrading a project from 5.1 to latest 5.3.2 (monodevelop 5.9.6) does not give me a list of files in the solution view and searching for text by *.js gives no results - what’s wrong?

Edit - fixed after side by side versions of Unity removed - unsure of issue cause
