SOLVED [json] problem

Hi,
Since last week I'm having problems opening rfactor 2, when I'm going to open the single player I get the error message appended below, however the dev mode does work.
I formatted and the problem persists.

 

Formatted what?
You format a hard drive which basically deletes all the data on it.

With your error I would have cut your player.json and paste it on your desktop.
Do a Steam verify games files and start the game.
You will have a default player.json then.
If that doesn't work it may be another of the json files.

edit, Do this first as it may tell you the exact problem:
To start rF2 with log, just add in the launcher settings (TAB SinglePlayer) +trace=3

//Edit: log files should appear in .\Steam\SteamApps\common\rFactor 2\UserData\Log
as trace<date>.txt

(there you go Juergen, passing on the log file "secret")

 

Any chance that an AV is blocking the file?

 

Is a json file something that could do make a AV program flag it.
They aren't executables or bats.
Just trying to learn my new thing for the day Juergen.

 

JSON files are at least...java script files. rF2 is opening some .json files during start up.

And thanks for sharing the log hint

 

I think your player.json got corrupted. Just delet it and than it should work again.

 

Would suggest Iooking at https://forum.studio-397.com/index.php?threads/sensitive-on-input-format-decimal-symbol.54467/

TL;DR open your regional settings and set decimal separator to period, not comma, and see if it fixes your issue.
