Hard Crash when completing Cartie’s Quest

Resolved: I moved the bot to another node and was able to upgrade without crashing.

On Xbox Series X

I’m attempting to complete Cartie’s final quest (The Magnificent Seven (million)) but every time I try to update crystal bot for the 6th time, I get a hard crash that takes me back to my dashboard. I’m able to load back right where I left. But it is a 100% crash rate. I can continue with the floor as usual. But as soon as I go back to upgrade the crystal bot, another crash.
