Lightroom won't open after deleting video cache files, "Not Responding"

HI everyone,

My C: drive was out of control and after researching I deleted my Video Cache files manually from C:\Users\username\AppData\Local\Adobe\Lightroom\Caches\Video

I keep my library on a 😧 drive.

After I did this, Lightroom no longer launches. I've let it run for hours. It just starts, sits on the splash screen saying "Lightroom Catalog - Adobe Photoshop Lightroom (Not Responding).

I'm on Win2010 desktop. Everything was working up through when I deleted the Cache files. I have settings set to limit cahce size but it appears the cache grows beyond that limit. Also the PURGE CACHE didn't work when I pushed that button. I'm on LR 6.0 desktop version. Thanks!!
