This is very strange. I couldn't reproduce with your save on PC (Browser).
I happen to have an Android, but don't usually play TiTS on it. Created a test character in the Browser, crashed when exiting the shop.
Downloaded the APK. Didn't crash. But I fiddled with the 'Tooltip on Tap' option, beforehand. Now it doesn't crash regardless of setting.
Browser doesn't crash, ether, now that I've changed 'Tooltip on Tap' once. I've no idea if it's related. It might be a bizzare one-off.
