I found a workaround to this crash...
It involves writing the layout name in the search field before unchecking the checkbox.
I knew that I wanted Unijoy layout. So:
1. I opened the Input method settings (System Settings -> Personalization -> Regional Settings -> Input method tab)
2. Before unchecking, I wrote "unijoy" in the search box just below "Available Input Method" (I had to install fcitx-m17n for unijoy layout.)
3. I unchecked the checkbox, and I found the layout I was looking for!
