@BMilan thanks for the help just found out it had a motherboard failure lucky i had warranty lol.

@WhyAreYouReadingThis I rolled my Nvidia drivers back to an earlier version that I knew worked. You can search up drivers for your system >>here<<

@BMilan im having the same problem with my gtx 1050 can you tell me how i can fix it?

@BMilan That's great! Thanks for following up and letting us know what the issue was.

@AndrewGarrison Last update: I managed to roll back my drivers to an earlier version, now I can use the game with the dedicated graphics card again :D

@BMilan I'm glad to hear you have found a workaround! I really wasn't sure what else to try. Hopefully, they will patch those drivers soon!

@AndrewGarrison Okay so, at this point it's clear that something is wrong with the nvidia graphics card so I just set the game to use my integrated one and suddenly it works again. I suspect that the latest driver update I installed causes the problem so I'm just gonna wait for the next update and hoping that that one will solve it, until then, I'll use the game with the integrated card.
Thank you for trying to help :)

@AndrewGarrison Well I updated my graphics card drivers through Nvidia's Geforce exprience app and the whole problem only started after that. I tried reinstalling the driver updates now, as well as manually looking for the latest driver updates on nvidia's website and installing that but none of those solved the problem. As for reinstalling DirectX, I have no idea how to do that, I tried looking for it on the internet but nothing worked, every directx installer I found says that I have the latest version of DirectX and there's no need for installation.

@BMilan You’re getting a lot of errors related to your graphics card or your possibly your DirectX install. You should first try updating your graphics card drivers and if that doesn’t work then you might need to reinstall DirectX.

@BogdanX @AndrewGarrison None of these worked :(
But here's the link for the output log you asked for:
link3

The log file in the appdata is the one you would want:
%UserProfile%\AppData\LocalLow\Jundroo\SimplePlanes\output_log.txt

You could also try renaming your Settings.xml file in that same folder to Settings.xml.backup and see if that helps. The next step would be renaming the SimplePlanes folder at%UserProfile%\AppData\LocalLow\Jundroo to SimplePlanes.Backup

@AndrewGarrison There's none (since the game can't even properly start up it probably doesn't create one) the only log file that is created is the one in the second link (that one isn't created in the game the Steam game library in theSimplePlanes_Data folder, but instead in AppData/LocalLow/Jundroo/Simpleplanes/)

@BMilan Can I get a log file after it crashes when you have all mods removed?

@AndrewGarrison I also unsubscribed from all of the steam workshop mods

@AndrewGarrison I tried removing the mod folder completely (placing it outside of the game library) as well as doing a clean install but it didn't solve the problem

I would recommend disabling all of your mods first to ensure they are not causing the game to crash. The easiest way to do that is to rename your mods folder temporarily. If that does fix the issue, then you can try copying mods back into the mods folder one at a time to indentify which is causing the game to crash.

@AndrewGarrison
Here are links to my output logs maybe that helps:
