The OP’s problem in the other thread seems to be freezing when sleep is initiated, not on wakeup. Even if it was the same problem it wouldn’t necessarily have the same solution.
I’ve had a similar issue with kernels 6.11, 6.12, and 6.13-rc. No suspend issue with 6.6.
The system shows the lockscreen (gray background as configured in swaylock), but freezes completely upon waking up.
