Reinstall on a Different Drive

We were able to overcome this issue by reinstalling the game on a different disk drive. Although the game was installed on the C: drive already, reinstalling on a separate SSD hard drive resolved the issue and allowed us to continue into the game. Credit goes to users on the Battle.net forums who uncovered the fix to this troublesome bug.

Other Potential Fixes

If the above solution didn't work for you, the solutions below might help your issue. Although they didn't work for our team, they have been reported to work for some users, so they are worth trying if you're still hitting a wall.

Play the Game in a Window

By pressing Alt + Enter after starting up the game, you can play the game in a windowed mode instead of fullscreen.

Although the game will still crash after reaching the login screen in our experience, we were able to make it past the initial title screen with this adjustment.

Try Starting Battle.net as Administrator

Some users have reported that selecting the Run as administrator option on the Battle.net app, then selecting Diablo 4 for them has helped them start the game.

Although we haven't managed to achieve success with this method so far, it has worked for some users, so it is worth trying for everyone experiencing this issue.

Crashes on Startup Screen

This bug occurs when starting up the game and entering the login queue for the first time, at which time the game will crash.

After this occurs, the game will crash on the title screen every time, and becomes unable to return to the previously accessed login screen.
