Lightroom Classic 10.3 - 2 years of photos gone after catalog upgrade

[negative459]

(Windows 10) I worked for hours editing a couple hundred photos today. I went to export them and LC errored in mid process because of a space issue on the target drive. I tried to cancel the export but LR wouldn't seem to do it so I exited out and restarted. When LC launched it asked me to upgrade my catalog, so I did. When it finished launching I am missing my last two years or so of imports. I looked online for solutions and have tried to open a different catalog but when I do it asks me to upgrade that one before opening as well, and I'm afraid to do it in case that's what got me here in the first place. Please advise.

Nevermind. Issue resolved. I found my most recent catalog in a wayward folder.
