Cannot open Echoes maybe 50% of the time

I’m experiencing a fairly pervasive issue in which I cannot go into echoes. When I try, maybe 50% of the time, I don’t get past the loading screen (and I’ve waited for 10+ minutes (when it usually takes maybe 4 seconds to load)). When I close the game, I need to avoid that echo or it will hang again. When I find an echo that works, then I’ll have lost stability, as if I entered that echo and died.
