@pedromassango just got this same issue... what works for me right now was these steps hopefully works for you as well. I was on master so: kill the IOS simulator then open a new one |
Unfortunately this doesn't work for me. It only happens in beta, not stable. Not sure if it's a factor, but I'm using M1 chip. |

Just ran into this, and thought I'd offer some observations:

We cherry-picked a workaround to stable in 1.25 where a So if you are seeing this issue on any current channel after a |
