How to remove the large folder section newly appeared at the bottom of the Windows 10 Start Menu?

After starting the computer and installing WizTree, a section organized in large folders suddenly appeared at the bottom of the Start Menu. This area is poorly categorized and does not match my personal usage habits. I wish to completely remove it or restore the previous clean layout. I am unsure if this change was caused by the installation of WizTree, but it is more likely that system settings were unintentionally modified. However, I cannot find the corresponding adjustment options in the settings.
