When my Adobe Creative Cloud is aktivated all the Letters show up double over each other and the font collection shows the used fonts as ?????????????????
When i turn of the Cloud and Minion Pro is not available with the default font all looks fine .
Similar problem here.
As a workaround try delete the file AdobeFntComposite.lst in the preferences folder (/User/Library/Preferences/Adobe InDesign/Version 16.0/en_GB)
By now it worked for me but I think this is not a definitive solution.
