MTaS not loading

Bought this for my wife for Christmas and so we could potentially play multiplayer somewhen down the line. On my PC, it loads perfectly. On hers, it drops back to desktop after the two logo screens. No error. Her log has the messages that BacktraceCrashpadWindows could not load a dependency (removing the file removes the error completely) and later that BacktraceCrashpadWindows and EOSSDK-Win64-Shipping could not be loaded (DLLNotFoundException). Both do exist in the correct folder according to the line in the log indicating where the plugin folder is set.

Edit: Fixed? Uninstalled and reinstalled both vcredist 2015 and 2019. I think it was missing 2015 x64 but that can't be installed with 2019 in place.
