I finally managed to get my phone running CrDroid after first messing up the installation and soft bricking the phone. For anyone having similar troubles this is what I did.
First off, use the command prompt (cmd), not powershell since powershell does not seem to support sideloading.
Edit 1: Tested this with updating OOS all the way to Android 13 before firmware flasher and it also works.

- Use MSM Download Tool to get the phone to Android 11. To use the tool put the phone in EDL mode by powering it off, hold volume up + down and connect it to your computer with a USB cable and hit start in MSM.
- Use the OOS build in updater to update the phone. The updater says it will update to Android 13 but it will not. Instead it makes incremental updates moving from 11 over 12 to 13. Once it gets to 12 you are done updating.
- Unlock the bootloader. In developer settings there is either an Advanced restart option which adds three dots to the power menu where you can get to the bootloader. Or there is a USB Debug options so you can get to the bootloader with adb reboot bootloader.
- Get to the bootloader again after unlock and run the Update-firmware.bat from C.63 Firmware Flasher mentioned in the OP. It will prompt three warnings during flashing but this is okay.
- Your phone should be in recovery now. Do a factory reset. Sideload CrDroid, reboot to recovery and sideload Gapps. Reboot system and rejoice.
