The "Black Steel in the Hour of Chaos" mission in Cyberpunk 2077 has been causing frustration for some players, as the mission still shows the task to talk to Yoko with no new dialogue options after everything seems to have been completed. Fortunately, there are several possible solutions to this issue.
One solution that has been suggested by a Reddit user is to try restarting or resetting the quest objectives on PC. This seems to have been effective for some players, so it may be worth a try. To do this, simply open the quest journal and select the "Black Steel in the Hour of Chaos" mission. Then, select the "Quest Objectives" tab and reset the objectives. This should trigger the mission to update and provide new dialogue options.
Another potential solution is to wait for a patch from the developers to fix the bug. CD Projekt Red has a history of releasing patches to address bugs and issues in their games, so it's likely that they will eventually release a patch for Cyberpunk 2077 as well. In the meantime, players can try some of the other solutions listed here to see if they work.
Some players have also suggested that the issue may be related to the quest order, and that talking to Yoko before completing the main quest may be causing the bug. In this case, players may need to backtrack and complete the quest in the correct order. This can be done by replaying the main quest and completing it before talking to Yoko.
Overall, there are several potential solutions to the issue of the "Black Steel in the Hour of Chaos" mission still showing the task to talk to Yoko with no new dialogue options after completing everything. Players may need to try a combination of these solutions to find the one that works for them. Restarting the quest objectives, waiting for a patch, and ensuring that the quest is completed in the correct order are all viable options to consider.
