Brief description of the issue:

Upon launch of the Sim from the steam client. It will progress through the load screen, pass the updater client, and get about 75% of the way through the load and then I recieve the exception. On the MicrosoftGeoSpatialTiles.dll ->> Assertion failed (MSVCPP Redist~ Runtime error on loading of Sim). No changes whatsoever to system since last flight. I’ve already been through all the usual fixes for this error (deleting the files in \users[username]\AppData\Local\FlightSimulator, the MS Apps in the other temp/cache location, the rollingcache.ccc file, etc…)
Working stable version of the VC++ Redistributables (no changes since last flight)
and I’m still getting this error on loading. I am able to click ignore about 4-5x and enter the sim sometimes, but sometimes it will just crash windows entirely.

I know this error has been around for awhile, but has anyone found anything recently for this particular exception (at line 108) of the MicrosoftGeoSpatialTiles.dll? Since I know other users have differrent variants of this issue.

Also I do have Visual Studio installed, but no Debuggers turned on (at least none that I know of), I mean I’ve been using this system arrangement for years and this just randomly started in the last 24hr with no changes to the system at all.
