OpenCore 0.5.9 stuck before picker screen

​

stuck at boot with OC 0.5.9

I've been using OpenCore 0.5.8 with Catalina 10.15.5, and everything works fine. Thought I should try 0.5.9 since it's out last week, however, I got stuck at this screen and couldn't see picker menu. I tried both debug and release versions, followed the upgrade OC section in the vanilla guide and updated config.plist as well as all kexts.

Could someone point me what might be the issue? Thanks
