I’m assuming the PC crashed on that occasion as unfortunately no crash data has been produced within the log.
By default and with any Ryzen CPU we recommend that you try lowering your ‘Worker Thread’ count down to 6 which will reduce the heat produced by the CPU. You may also wish to try switching to DirectX 11 - both of which can be done within the launcher.
Otherwise, the PC actually losing responsiveness indicates something else could be at play, such as a driver instability or overheating. There may be some leads in the Windows Event Viewer.
