From the log which ends while it was getting Navdata data from the sim, it's possible that the sim took more than usual to reply, and if you open the menu while it's still getting the data, it won't work.
Either wait a bit more before opening the menu (and exit a session with the GSX Toolbar icon Inactive), or disable all other add-ons that have modules in the exe.xml (this is obviously for troubleshooting reasons), because one of them might be causing this and fact you seemed to have noticed a difference when changing the loading order, seems to confirm this.
