I can't get Darktable to work anymore

After everything, completely fresh install of windows, no updates.
The log file contains the same line as previous:
"Magick: caught exception 0xC0000005 “Access Vision”. …Magick: caught exception 0xC0000005 “Access Vision”…

At this point, I’m pretty disgusted with the whole thing… I’ve spent the last year learning DT, and loved it.
Looks like I’ll have to scrap it.
