I received the following solution to the problem from the tech support, must say I was impressed to get an answer within 24 hours, well done WG!
I won't be able to try these solutions for a couple of hours so just passing on WG's info in the hope it helps others out, although it may be worth raising your own tickets with logs and dxdiags for your own systems in case we're experiencing different issues;
Problem is with game detecting input hardware it cannot recognize and it doesn't know how to utilize. So the game simply ends its own process.
That device can be a mouse/keyboard not recognized as valid by the game or a bit more uncommon device - like a remote for a printer (or a TV/screen) etc.
There's two potential causes:
1) Game files. Our game is meant to hold information about controllers (and exact key binds for each controller) in a set of files. If those files - for whatever reason - get corrupted, the game wouldn't be able to read those files and errors like the one seen in the log files would appear.
Solution in this case is very simple: Delete input_mapping folder.
Simply press and hold WIN+R keys at the same time, in the RUN window paste the following: AppData\Roaming\wargaming.net\World of Warplanes
Then hit OK button and you will find input_mapping there.
After deleting the folder, try to run the game again and see what happens.
2) Hardware - ie. the source of the error is piece of hardware connected to the device, which the game cannot identify.
In this case I will need you to remove/disable all devices connected to the PC, with the exception of mouse and keyboard. Even if something is wireless, it will have to be disabled. Once that is done, try to run the game and see what happens. If the issue persists and you have such capability - try to run the game with a different mouse model and a different keyboard.
Once you have identified the device causing this problem, please send us a link to a store page (or product page) for this device. It will allow me to send a request to the dev team and hopefully this device will be added as recognizable by the game.
