Premiere Pro Timeline Issues

So it would appear that (once again) the most recent update has caused some sort of issue with Premiere working for me. For whatever reason, when I try to work with something in my timeline, it will either not respond to any inputs, it will have parts or entirely gray out (see image), or just crash.
Is anyone else experiencing this issue and/or have a solution as to what the problem is? I'm working with the same file types and constraints that I have been for months now without issue until the past few days.
