Issues with MSFS Crashing & Updating

Hello there fellow simmer! It sounds like you're experiencing a couple of issues with your Microsoft Flight Simulator (2020 release) and I'm more than happy to help you troubleshoot and resolve these problems. I've faced a similar situation before, so let's dive into the two main issues you've mentioned: the Alaska Bush Trip crashing and problems with updating.

1. Alaska Bush Trip Crashing

Crashes during the loading of bush trips are often caused by corrupted files or incompatibilities with the installed addons. To troubleshoot this issue, you can try the following steps:

1. Make sure your graphics drivers are up-to-date. Visit your GPU manufacturer's website (NVIDIA or AMD) and download the latest driver for your graphics card.
2. Disable any third-party addons, such as liveries, scenery, or utilities. You can do this by moving the relevant folders out of the "Community" folder located in the MSFS installation directory.
3. Delete the rolling cache in the sim. Go to Options > General > Data > Delete Rolling Cache and click on Save & Restart to apply the changes.

If the issue persists after following these steps, you might want to try reinstalling the Alaska Bush Trip challenge.

2. Updating Issues

The issue you're facing with updating the World Update USA file and the Points of Interest might be due to a version mismatch between the content and the sim itself. To resolve this problem, you can try the following:

1. Make sure your sim is updated to the latest version. You can check for updates by launching the Microsoft Store and navigating to Downloads and Updates. Click on Get Updates to ensure the latest version is installed.
2. If you're using the Steam version, right-click on Microsoft Flight Simulator in your Steam library, select Properties, and navigate to the Updates tab. Ensure that the Automatic updates option is enabled.
3. Clear the download cache for the sim by going to the folder where the content is downloaded and deleting the files manually. The default folder location is C:\Users<username>\AppData\Roaming\Microsoft Flight Simulator\Packages. Please note that this will remove all downloaded content, and you'll have to download them again.

As for FSUIPC and the map programs, they shouldn't cause these issues unless they are conflicting with other addons or the base sim. To ensure they are not causing the problem, you can temporarily remove them from the "Community" folder and check if the issues persist.

I hope these suggestions help you resolve the issues you're facing with MSFS. Remember to have fun and enjoy the skies! If you have any further questions or concerns, don't hesitate to ask. Happy flying!
