I think you may be missing the point of what Safe Mode is for. It’s not to use regularly. It’s specifically to test for stability if you’re having CTD issues with 3rd party (both community and store) add-ons.
A lot of CTDs are caused by plugins. Not all, but many are. The idea is to run in safe mode without ANY 3rd party plugins, either community or marketplace. That lets you test if your sim is working correctly in a 100% vanilla state.
If you’re able to run MSFS in safe mode without crashing, but it crashes when you load in normal mode with your add-ons, then it means one or more of your plugins are likely causing the crash. It’s the up to you to troubleshoot and figure out what the bad plugin is.
If you sim crashes with safe mode, then you have some bigger problems.
That’s the point of safe mode.
