Is your battery ok? Mine have status 'Service recommended'. I guess this is the reason.Yes, my Macbook Pro does the same. However, it's been like this for a long time, ever since I switched to OCLP.
I found the same problem here, but it didn't help me.
I think I've found a fix by making two changes. I haven't done much testing yet, but the computer does not seem to be shutting down completely when going into hibernation mode anymore.
1. Download the TUI version of OpenCore, and set the following to True
Patcher Settings -> Miscellaneous Settings -> Set Hibernation Workaround
2. Build and install OpenCore to your computer.
The following steps might not be necessary, but should probably be done regardless if you have an NVMe SSD installed in your Mac:
3. Once OpenCore has been installed to the EFI partition, download SsdPmEnabler (https://github.com/kvic-z/SsdPmEnabler), mount the EFI partition (using https://github.com/corpnewt/MountEFI for example) and copy the SsdPmEnabler.kext into EFI/OC/Kexts
4. Edit the EFI/OC/config.plist file so that it loads the SsdPmEnabler kext at boot (using https://mackie100projects.altervista.org/opencore-configurator/ for example)
So, I returned to Big Sur because it works better for me (without any issues like hash volume or hibernation mode).
