Temporary fix just to get it running on i3 :
Open /usr/lib/caprine/dist-js/index.js on line 190 with an editor as sudo and replace:
lastWindowState.x,
lastWindowState.y,
lastWindowState.width,
lastWindowState.height
on the x,y,width,height arguments respectively with some integer like 0,0,100,100 respectively. Remember to keep the comma after the number.
Should startup afterwards. Hope I could help

It worked for me, thanks!

Building on what @PanagiotisGts recommended, I modified line 181 from

const lastWindowState = config_1.default.get('lastWindowState');

to

const lastWindowState = config_1.default.get('lastWindowState') || { x:0, y:0, width:100, height:100 };

and that solved my issue in manjaro :)
