Processing Canon CR3 files fail since upgrading to latest version

After upgrading to latest pureraw version my Canon CR3 files fail to process correctly most of the time. They end up being all black except for a couple of colored triangles in upper left corner. I reinstalled both LR Classic and Pureraw. Windows 10 machine.

Same issue here IF I process the file in Lightroom before evoking PureRaw. Make no changes before running PureRaw and no issue.
