Simple trick if msfs2024 gets stuck 93 to 99% loading.

Don't stop a partially loaded MSFS2024 with the X at the window top. Instead open task manager and kill it there. This method seems to erase the partially created incomplete files that MSFS creates during the loading process. Otherwise that incomplete (corrupt) file will hang around and continue to block you at the loading process every time you boot up.

Another method that is more involved but can work as last resort is to exit the beta version of MSFS if you are in the beta. Or join the beta if you are not in the beta. Because this starts a new loading process with new files being created as MSFS loads. Of course there is not always a current beta available. At such times this method cannot be used.
