Hi XXXLH,
I am not with Laminar Research; just a flight simmer from downunder.
I have opened your log.txt file. There is "good" news and "bad" news. Unfortunately I cannot offer any "good" news.
1.. Your log.txt file is probably the longest file I have ever seen. This is most likely due to the number of errors in your system that automatically lists in the log.txt file when you either crash or shut down. A simple fix to one issue may fix everything else otherwise you may need to perform a complete deletion of your X-Plane version with a complete reinstall and then progressively add your plugins/addons one at a time checking your log.txt file to ascertain if an error appears after each individual install
2. Your log.txt file tells me you have a steam version of X-Plane. I don't support steam versions and normally do not comment on problems. You are lucky that I have made the comment in point 1 above.
This forum is for x-plane flight simmers using the official and original version of X-Plane from Laminar Research. You should seek the help you are asking from a steam forum. You might check X-Plane.org ( no association with Laminar Research at X-Plane.com) or the steam forum that may exist from your point of purchase.
The steam version of X-Plane is a 3rd party hybrid that has been modified from the official Laminar version and is taking a commercial advantage of the development work carried out by Laminar. It installs differently to the Laminar version. Updates are late and you cannot mix and match either versions particularly if and when a beta version is released by Laminar.
Because you are running a steam version I will not question whether you have multiple legal copies of the software. Have a look at the following link found at https://x-plane.com/manuals/desktop/#networkedmultiplayer
