No. I deleted all the mods via CKAN, then deleted all the subfolders from "GameData", except for "Squad" and got the same error. And I do not have a subfolder of "FShangarExtender" in "GameData".
UPD
I apologize, it was on another computer. I'm not sure if the folder "FShangarExtende" is deleted, I'll check it later.

Other comp, clean STEAM KSP, only "Squad" in "GameData", same error:
