sleep/wakeup issue on Sonoma 14.5，OC 1.5.0, with iMac 2015 later 5k

install Sonoma 14.5 with OpenCore Legacy Patcher, everything is OK but sleep issue.

The system cannot be woken up after sleep, and the system crashes. I have seen many questions about sleep issue, various models and versions. Is there a solution to this problem?
