I have a question y is lift off not running on my computer it says liftoff is not responsive.exe pls help I have used it before and it worked perfectly fine
That could be due to any number of reasons. Can you record a video of the error, beginning at your desktop and showing the launch attempt? That would give us more to work with.
Was liftoff installed and working on the computer before and it just started giving that error? Or did you just reinstall it? If its been installed for a while and it just stopped working you could try deleting the app and then reinstalling it.
I just did some research... First thing you can do is go to task manager and end all tasks that are related to steam. Then retry opening it. Next you can run the game as administrator. Another problem is that your GPU drivers can be outdated. That can lead to freezing.
Some other ways to fix it are deleting the game using C:\Program Files (x86)\Steam\steamapps\common\ then when there just delete the whole game folder. It can also be an antivirus blocking the game (this has happened to me before).
