Have been using MSFS 2020 for 3 years without this problem but starting several months ago I can not activate LNAV/NAV in airliners and the Cessna Citation CJ4. Oddly enough it does activate in the Cessna Citation Longitude, as well as in all turboprops. Uninstalling and reinstalling MSFS 2020 did not fix it. All software updates are applied. Would appreciate any ideas to resolve this issue.
I can’t help you spherically except to say I suspect it is something in your FMS or Autopilot setup or both. LNAV/NAV work in the B787-8 & 10, B737, AB320 and the Longitude in my system. I’m thinking it’s not a problem with the Sim. Maybe someone else can be more specific.
Good luck.

You need to seriously checkout a CJ4 flight tutorial, and learn the rules of NAV/LNAV/ and also VNAV engagement. The plane has really been good, since the release of the AAU2 update.
