Could you try module parameter rtw_disable_lps_deep_mode=1 to see
if it can work?
If it works, I suggest to apply below code:
diff --git a/main.c b/main.c
index 3f7a5d54..3bb07898 100644
--- a/main.c
+++ b/main.c
@@ -1345,6 +1345,9 @@ static enum rtw_lps_deep_mode rtw_update_lps_deep_mode(struct rtw_dev *rtwdev,
