Inside the same directory folder as your project file, you'll find a folder called Adobe Premiere Elements Previews. Inside here you'll find old auto-saves of your project. Can you find one that predates your glitch?
That's the easiest way. If that doesn't work, I'm not sure how to get back to before the glitch.
BTW, you're not seeing 15,000 clips in your Project Assets folder, right? And is this number otherwise affecting the program's performance or how long it takes the program to load the project?
No, I cannot go back to a previous auto-saved version. I've done far too much work since it started to glitch.
What's the file tree path to the "Project Assets" folder? Let me know, and I'll look to see how many things/clips are in it.
There is no tree path for the Project Assets folder.
The assets are wherever you've stored them on your hard drive?
So you're saying you have 15,000 items in your Project Assets panel?
No, there are not 15,000+ items in my Project Assets panel (panel). The assets that appear in my Project Assets panel are, for the most part, the video clips and music tracks used in the project. Also, two instances of a motion title (a pre-built one that comes with PE14) appear. Even though the two motion titles are marked as "Used," they in fact are not in the project. I assume this is contributing to the glitch.
The 15,000+ number (count) appears when the project is opened. It appears along the bottom of my screen. After a while, probably a minute or two, the bottom of the screen will, finally, say "All media loaded."
This looks like more than a glitch. It looks like a full-on project corruption! I just don't know what would have contributed to it.
It might be best to contact Customer Support via Chat and see if they can figure out what's up. This definitely is an anomaly!
