Basically, I built a player HUD to see stamina when playing the game. Super simple. Works perfectly. But after saving and exiting, when I relaunch the project it crashes. I can provide crash logs upon request. As a check, I simply recreated my HUD and widget from scratch, compiled and played it in the game just fine and same results when I went to reopen the project.
