BetterTouchTool crashes when trying to import settings from BetterSnapTool

I wanted to import the settings from BetterSnapTool to BTT and did the following from configuration.

Configuration > Window Snapping & Moving > Snap Areas> "Import existing Snap Areas from BetterSnapTool(experimental)"

The moment I pressed the button, BTT crashed, and when I restarted it, the settings were not imported, I tried with and without BetterSnapTool running, and in both cases, BTT crashed. (BetterSnapTool does not crash.)

I understand that importing settings from BetterSnapTools is an experimental feature, but I'm reporting this in the hope that it will help with development.

I'm a Japanese user and I usually use BTT in a Japanese environment. I temporarily changed the language setting of BTT to English for reporting purposes, but the problem remains the same.

Device Infomation
MacBook Pro 15" 2018
macOS 10.15.7(19H15)
