Totalfinder Windows flash and disappear

Hi, hoping someone can help.
Up until very recently, Totalfinder 1.4.23 was playing nicely with Mavericks DP7, and then all of a sudden any attempts to open a finder Window results in a quick flash and then… nothing.

There are some exceptions - one of two connected servers will open in a Finder Window, but others and external drives, and even the main drive itself do not.

If I use Spaces to see if Finder windows are open, I can see that they are but they appear only with the Finder icon and as a very tall blue window without any preview content…

Any help appreciated - I have uninstalled and reinstalled Totalfinder repeatedly, including using AppZapper and rebooting. Nothing has fixed this yet!

Thanks

Hi,

Isn’t TotalFinder silently crashing? When you go to Console.app -> User Diagnostics Reports aren’t there piling up files beginning with Finder_something ?

Yes, there are multiple entries - some are quite lengthy. Is there any specific section that you might be able to look at to determine a cause?
Here is the first section of one log:

please send me full file(s) to crash-reports@binaryage.com

Same situation with 1.4.24… though opening a new Finder window from the dock works fine, opening other finder windows does not; nothing I can see in the crash log…
