Roboto TTF replaced with OTF in InDesign 21.4 > causing missing font errors

When I/we open a document Indesign, it throws up a "missing font notification" for the Roboto TT font (and condensed).

Then, when we open creative cloud and click on active fonts, there is a ‘refresh symbol’ but nothing loads/activates. 

We’ve worked through every soultion we can find, yet the issue remains. It has affected everyone on the studio, so is not machine specific.

Please advise, as this will potentially create many hours of work going through templates and documents to resolve this.

Thank you in advance,

Dan. B
