You might experiment with using dtbo.img + vbmeta.img from the /e/OS image rather than the source I commented on in Post #2.
I produced these by modifying this method OnePlus - 9 Pro - lemonadep - Documentation Suggestions - #8 by bofh666 – using in this case as a “source file” e-1.10-s-20230413279105-dev-hotdogb.zip. See Method below.

I am not certain how much of the process might have to be repeated, but essentially you would go back to the section titled
Flashing additional partitions
-
Manually reboot into bootloader or download mode.
With the device powered off
hold Volume Up + Volume Down + Power. -
Flash the above image files to your device by typing
fastboot flash dtbo e-1.10-s-2023-04-13-dev-hotdogb_dtbo.img
fastboot flash vbmeta e-1.10-s-2023-04-13-dev-hotdogb_vbmeta.img
If you are lucky you can drop out of fastboot to recovery with
hold Volume Down + Power
If at first it fails you may have to repeat the remainder of /e/ install process.
Edit In light of the inconvenience of “cannot power down”, one would probably best run the whole install procedure starting from the revised Flashing additional partitions
Should you encounter Qualcomm crashdump mode, you could reflash the Android 12 stock ROM
… or use that downloaded ROM to follow this https://wiki.lineageos.org/devices/hotdogb/fw_update. At time of writing, this last link is at Android 12
Method
- Download /e/OS ROM e-1.10-s-20230413279105-dev-hotdogb.zip to ~/TEMP/
- Download https://github.com/ssut/payload-dumper-go/releases to ~/TEMP/
and extract here → ~/TEMP/payload-dumper-go_1.2.2_linux_amd64 - open terminal
cd ~/TEMP/and extract payload.bin:unzip e-1.10-s-20230413279105-dev-hotdogb.zip payload.bin - extract payload-dumper-go:
tar xzvf payload-dumper-go_1.2.2_linux_amd64.tar.gz payload-dumper-go - run
./payload-dumper-go -partitions dtbo,vbmeta -o . payload.bin - Make shareable
