I’m trying again to get it working... Starts in dev mode but not normal? Win 10 pro, tried all the usual suggestions.
Probably need a few more details if anyone is to help you as this is not what happens when everyone else presses the rf2 button. Ever tried starting it from a shortcut?
Could be a corrupted file in your rF2 profile. Move your ..\rFactor 2\UserData\ folder to another place and run rF2. This will create a new UserData folder. In case this works, you'll have to config everything again.
I had the same issue and let the game create a new userdata folder but it is not possible to restore any information from my saved old userfolder... why is that? So i dont need tho make any backup because it is useless - if i copy any of my old files back in the new folder (player.json, controller.json, ...) it does nothing - no information are reaching the game anymore - so i have to edit everything new... all the fucking mirror settings, seat settings, all plugins for my wheel, simhub, all keyboard controlls all wheel settings - this is very annoying and a real showstoper ... and it is not clear what destroys the userdata folder ... yesterday i played the game - 8 hours later its broken and cant be restored - this makes me so angry!
When you have the Problem and rename your UserData Folder before you start the Game, to get a fresh one with that it works again, move Files like the player.JSON, Controller.Json, your own Controller.JSON, if you have one, Plugins, .... one after the other back into the working UserData Folder, to identify the one that causes the Problem. And did you already try it with running rFactor 2 as an Administrator? Maybe it's a Problem with Windows User Rights.
