Premiere Pro suddenly crashing way too much?
Current CC, working with projects I've worked with before. Oh, underlying platform is Windows 10. Windows installation and underlying hardware months to a few years old, used heavily with Premiere Pro all that time.
Went back to some ongoing projects, and I'm finding one of them *always* crashes on load now (was fine before; redundant filesystem with weekly scrubs to verify file integrity tell me the file is the same, but now Premiere crashes loading it), and I've now encountered another case where I can crash it consistently with a particular action (creating a sequence from a particular clip, or dragging that clip into a sequence).
Was intending to get this editing done tonight, but can't seem to make that happen; deleting my current copy of the clip and reimporting doesn't help, creating a new sequence one of several ways doesn't help, etc. When I drag the clip into the sequence it makes a "bong" noise, than shortly after that pops up the dialog telling me Premiere Pro has stopped.
Ongoing project, the clip isn't new, etc. Clip plays fine on its own and in Premiere, but adding it to a sequence reliably crashes Premiere.
One obvious approach would be to fall back to the last version, but that will be annoying since I had to upgrade a bunch of other projects to go to that version; presumably if I roll back, I'll lose access to those upgraded projects. Any other ideas?
