    Hi,
    When I start RFactor2, I receive this message : " [JSON] failed to perform operation, unsupported type "
    I don't know that one.
    I checked the local files, it's okay, no problem.
    Do you have any idea of the research to be carried out?
    Thanks.

    Most likely you had lock-up or crash of rF2 as it exited a track session. Several .json files are re-written with new data after every visit to a track, so one of them might have been mangled. You can try installing fresh versions by renaming the extention from .json to .jsXXXon. That will cause steam to download a fresh version of the file AND allow you to easily find it if you want to revert to the older version. A simpler method is the copy the Player folder outside of rF2 and let steam rebuild the entire player folder. That should cover most .json files.

    Hi,
    I rename the player folder then Steam rebuilt the missing folder and now I think that the game seems to be working fine.
    Thank you very much @davehenrie
