Crash Unreal Engine 4 with computer stuck

crash Unreal Engine 4 with computer stuck.
crash after 1s. - 60s.
i cant find crash dump in C:\Program Files\Epic Games\UE_4.26\Engine\Programs\CrashReportClient.
downloaded in standart folder.
start UN4 in Epic Games Launcher.
reinstalled windows.

Have you installed the newest NVDIA driver? 461.40 studio driver caused these crashes for me, freezing the whole system. Reverting to 460.89 studio driver solved the issue, everything is running smoothly again.

Thank you. How this work?

Download the 460.89 driver installer manually here Geforce Driver Results | NVIDIA
Uninstall your current driver in win 10 under settings/apps, restart and install the downloaded package.
