I followed the article line by line on My MacBook Air 2017. And I'm still getting the error saying "There was an error parsing the Info.plist for the bundle at URL <0x7fcd3c7ad600>: NSCocoaErrorDomain - 3840". Any idea why is it so?
I'm using Mac OS Catalina 10.15.7. Install disk has 32 GB of disk space available.
MacBook Air 13″, macOS 10.15
Try creating the macOS USB installer while booted into Safe Mode in case some third party software is interfering with the normal operation of macOS (typically it would be anti-virus apps, cleaning apps, and third party security software -- none of which are needed on a Mac).
Perhaps the installer is corrupt. Delete the installer from the Applications folder and empty the Trash. Download the Catalina installer again to try creating the USB stick again.
You may even want to run Disk Utility First Aid on your macOS volume (even better to run it on the hidden Container). Within Disk Utility click "View" and select "Show All Devices" so that the hidden Container appear on the left pane of Disk Utility. Even if First Aid shows everything is "Ok" click "Show Details" and manually scroll back through the report to see if there are any unfixed errors listed. If there are any unfixed errors listed, then you can try running First Aid from Recovery/Internet Recovery Mode, but if the errors still cannot be fixed, then you will need to erase the whole physical drive before restoring from a backup or clone. Disk Utility will give an error if you attempt to scan the Container after scanning any of the individual APFS volumes so you will need to reboot the computer to scan the hidden Container first.
As a last resort try using a different USB stick especially a different brand since the quality of USB sticks are extremely poor. I doubt this is the cause of the error you have listed since I would expect the error to be related to the downloaded Catalina installer app.

Try Option Booting by holding down the Option key immediately after hearing the startup chime in order to access the Apple boot picker menu. See if you can see the Monterey USB installer. If you don't see it here, then try creating the USB installer again using a different USB stick (another brand may be best) since Macs can be very picky about the USB sticks/drives used for booting.
Hi HWTech,
I downloaded the installer at-least 3 times. Finally I decided to give a try with Monterey installer and I was able to create the installer. I mean at least the process completed successfully. However I am unable to see bootable USB drive in the bootable devices.
So I guess there is some issue with the Catalina installer.
Hello,
I was able to create a bootable installer. As suggested I used a different pen drive and I had to give terminal full-disk access. Once this is done, setup was able to create a bootable disk.
Thanks for all the help.
