I reinstalled Fredo6_Tools to get a spin. Took it back out and relaunched without spin. This is the trace log from the previous session

Another strange effect of note: in the log viewer window, when I export TXT, that worked and a popup opened asking if I want to open the file. I clicked YES, and SketchUp went into a spin! This seems the same as how the Plugin Store window hangs...

A skp file contains a human-readable (ASCII) header at the very beginning of the file, identifying the specific version of SketchUp used. However, the bulk of the file is a proprietary binary format. File recovery programs have a poor track record reconstructing binary files.
