What is the Issue?

First thanks for providing a way to make my iMac live longer with the new nifty features on Monterey. I had 12.3 beta1 installed without any problem with the patcher 0.36 version. I updated with 0.42 and tried to install 12.3 beta 2 which failed using the „installed openCore Legacy Patcher on local disk“, 1- failed using MacOS update „update failed“ 2- failed using a USB stick - still using OCL patcher GUI

install on 12.3b2 on USB, build patcher install patcher on USB
Reboot „alt“ and EFI boot with „alt“
Choose installl macOS volume
Install runs OK
Once logged in: open OCL patcher to run the post-install volume patcher
Reboot …. And grey-white screen with flashing folder with interrogation point
Reboot with „ALt“ only sees macIntosch HD which evidently when select sends the „circle with cross in“

So computer does not boot after applying the volume patcher (3T fusion)

What steps have you taken to troubleshoot this?

Restart in recovery mode

diskutil GUI sees 2 volumes: MacIntosch HD and Update that are sharing the same partition (2 different volumes though)
Both verify OK in GUI
Open Terminal
Run command-line diskutil list
Sees 2 volumes: disk1 internal, physical with EFI and apple_APFS container , disk3 synthesized which contains HD data, -reboot etc… but does not contain a GUID partition table

So I tried to go back to some fundamentals — I reset my Fusion disk - reinstalled good old Catalina with security updates (old habit) and then install OCL patcher and lastest 12.2.1 no problem with then patching after the install. All this using a USB external so that apart from the App all is external prior to patching

then updated to 12.3b2 and same issues: installs fine even has universal control. Then Patch applied - reboot and again funky flashing folder with interrogation mark.
Reboot with ALT … and only sees a MacIntisch HD which when selected cannot boot and shows a circle with a cross inside. -reboot in recovery mode and in commanding diskutil: There is an unnamed volume which when verifyVolume is run shows at the time of verifying the superblocks: Error: apfs_sb at apfs_fs_index (4): apfs_incompatible_features has unsupported flag: (0x20) Volume superblock is invalid
