TotalFinder 1.12.3 bug: blank white window

Running macOS 10.15.5 (19F101), TotalFinder 1.12.3. Almost The computer turns on from sleep or I don’t use the finder a little long, I get a blank white window.
After I restart Finder everything is fine again. SIP is disabled and make sure totalfinder have the system events power.
by the way, open a new tab is also working, and blank white window seems to be with download folder.

Any ideas?

If you got the blank window, drag the blank window, and you will got the split windows.
why the window split two?
