Media Offline, Importer Reported a Generic Error, Cleared Cache/Trashed Settings, Project Now Missing

Folks, I'm at about the end of my rope here, and any assistance you can provide would be much appreciated.

I spent all of last Saturday stringing together a ~22 minute personal project in Adobe Premiere Pro for Windows 10, and finally got done editing tonight. I am a beginner that just downloaded the trial last week, but do have some brief video editing experience from middle school on Mac.

When I went to export the file, for some reason it kept only exporting one frame of the full project. Shortly after the second time this failed and I tried to get back into my Premier Pro window, the software crashed and subsequently crashed my PC. I didn't send an error report because I didn't think this was going to spiral into an out of control issue (I had several tabs open in Chrome at the time and chalked it up to that).

When I opened Adobe PP back up upon reboot and recovered the timeline of my project, I got a media offline error for a number of clips I had imported into the project area that I both did and did not end up using in the timeline. A couple of the clips I was able to link the media back to (all of them are still in the same local folder on my laptop that they were at the time I originally started the project, not an external drive), but most of them kept giving me a "the importer reported a generic error" message so I couldn't fix the media offline gaps in my project.

I combed through various forum posts regarding the generic error message and found almost no information regarding a specific fix other than clearing the cache and resetting the settings to default. So that's exactly what I did according to the instructions provided by the Adobe staff in the forums here: FAQ: How to clean (delete or trash) media cache files? . Now when I try to reopen Adobe PP, I can't even find my recent projects!

My brain is fried from troubleshooting at this point and I am just really hoping that all of my work this weekend wasn't for nothing. I can't even begin to put into words how frustrating it is to be ready to export a project, only to have the software crash and parts of the timeline sent offline for no apparent reason, and now it appears as if the entire project may be gone and I'll have to start all over again. Please help me before I lose my mind entirely.
