I'm hoping that someone can help with this, because I'm stuck.

Sometime in the last 3-4 days (was offline some so can't nail exactly), I can't bring up the GUI for Calibre 6.17 64-bit. The program starts, gives no errors, goes thru "loading books" and "initializing user interface, then shows up as "started" on the taskbar (I have it pined there). But when I mouse over the icon, it shows a picture of a totally white, blank calibre screen. Clicking does nothing. Even tried double clicking, although not needed in taskbar, but no joy.

Noted the following:

running 64-bit Calibre
"initialling user interface" sometimes comes up pretty fast, especially since I have over 65,000 books listed.
Renamed my primary library so it wouldn't load it, no help
Removed Calibre 6.17 (been using since it came out), installed Calibre 6.11 - no joy
uninstalling last system update didn't help
uninstalling last 2 Dell updates (from this timeframe) didn't help
Currently using Calibre Portable 16.7, and it opens with the current large database, and comes up fine. Ran Check Library from portable version, and it reports no issues. Obviously not a long term solution, but it keeping me going for now.
No hard disk issues reported on that drive (1 GB SSD with half the space free) - chkdsk p: /f /x
after opening dialog goes away, the computer is using 12% CPU and 16% memory (of 64 GB) and 0% Disk. When I'm doing heavy usage of Calibre, total Computer memory can go up to 40%+ (which is why I went from 32 to 64 gb memory)
Calibre is then showing one main program, using 0.1% memory and 962 MB memory, a worker process (0% CPU & 8.7MG memory) and a Console Windows host (0% CPU & 5.7 MB) None of these figures change for at the 10 min I monitored after opening dialog went away ("initializing user interface")

I really want my full featured Calibre back. Any help or other things to try would help.
