I click on background and it doesn't work! HELP

My name is Viktor and I'm the developer of the New Tab Studio.
Anybody who has the similar bug please provide me some additional information.

When did you install the extension? If yesterday or earlier please try to reproduce the bug in the new version: https://chrome.google.com/webstore/detail/new-tab-studio-countdown/epngggilgnflanfabeldfpbgponcgpgl

If the new version has the bug too, please provide me some more details:
1. What is your OS? (Chrome OS, Windows, Mac OS, Linux)
2. What is the version of your OS (Windows 8, macOS catalina, etc.)
3. "I click on a thyme, then I click on tour, which shows me how to edit, so I click on edit, and then I click on background, and it pulls up a new tab without the extension." -
a. what theme do you click?
b. How many steps of the tour you complete?
c. Does the extension crash after a click on the background button?
d. Do you see the background dialog?
e. Do you perform any other actions?
4. What is the version of your Chrome browser? (What is my Chrome version?)

More details your give - I reproduce the bug faster and resolve it.

Successfully reproduced on linux.
New version (3.2.7) with bugfix will be available after the review in Chrome Web Store (today or tomorrow)
