Hello everybody. I was sitting quietly editing the video, when suddenly I could not select a keyframe for the filter. Checked on others in the same way. When you try to select the keyframe icon, it turns blue and nothing happens. Already reinstalled the program, but it did not help. Tell me what to do Or, as a last resort, how to return the program to its original state, otherwise even after reinstalling it was in my settings.
Edit: Thank you very much, your advice helped me solve this problem) But I don’t know how to close this post
