I see the following errors and the QuESt window is closed when I try to go back to the previous window by clicking the button on the top left corner after I run valuation wizard and generate report.

Update: this issue is due to the version of Kivy; it works if using 2.0.0 or older, but this issue arises with version 2.1.0. Currently working on a fix.

@hchoi0211 I've been trying to replicate this problem but it is working normally for me. The list below is the step-by-step actions that I took; could you confirm if that is the situation where you received the error message?
