Locate the game directory on the system hard drive. The easiest way to do this is to open Steam, navigate to Library, then right-click on “F1 2019” from the list of games in the left-most column. Then put the mouse over Manage and then click Browse Local Files.

From the file list, locate these two files and delete them by selecting these two files (and only these two files) and pressing the DELETE key on the keyboard:
a. nvngx_dlisp.dll
b. nvngx_dlss.dll

Launch F1 2019 as normal.
