I just installed TotalSpaces 2.6.21 on El Capitan 10.11.6 (15G18013) and it crashes when you move Google Chrome windows from one space to another. This does not reproduce when I downgrade to 2.5.4:

I do have to say that I absolutely love TotalSpaces; I cannot use macOS without it and am so thankful that it was created. I hope that you guys are able to resolve this bug; please let me know if you require any additional information!
