On a Linux System using Proton, Wayland, FCITX5 (input system), a Japanese DVORAK layout, and custom remappings of all keybinds in order to match their expected keyboard positions (of importance here, Q/Inventory is remapped to the Colon Key, which is unique to the Japanese DVORAK Layout), if the Inventory key is pressed while in an editable condo, the game will crash.
Switching your keyboard layout to QWERTY will stop this crash from happening, and everything will work as expected.
This occurs on multiple Proton versions, however I can only confirm that this happens on my specific setup and layout.
