Try MSFS-AddonsLinker (or one of the others! There a few). Once you get around to understanding the logic in the program, it works very well. No need to erase and re-install add-ons, you can “turn off” add-ons to see if one of them is a problem. You can enable only the sceneries, aircraft, and airports you need for a flight.
