Start MSFS from Addons Linker

I always start MSFS from Addons Linker after selecting the addons I am going to use.

Yet lately, with no apparent reason, MSFS does not start using this procedure (I have to start it from the start menu and selecting MSFS). It seems that something has changed the properties of the MSFS exe file properties. It does not even work using a shortcut in the desktop to start the non-video (reduced loading time) version.

Does anyone have any suggestion on what should I look at to clear this issue?

Thanks!

There have been no updates to the sim, so I doubt that is the cause.
It could be a Windows update that changed something though.
Did you add MSFS addons in that time frame?
If so remove them.
If not, try uninstalling the linker, then reinstalling it.
See if that helps.

Thanks for your input!
