I just started using Tabox today and I am having this issue.
Chrome Version 106.0.5249.91 (Official Build) (64-bit)
Tabox version 3.5.7
Windows 10
I have disabled all of my other extensions except for this one. I have even removed and reinstalled Tabox, and disabled my anti-virus. No matter what I do, the first tab of the collection just opens as a blank "new tab"
