Monterey installer not showing up in OC bootpicker

Hi guys! I was trying to install Monterey but got stuck on the bootpicker because the installer does not show up there. I am using opencore 0.7.5. Other boot options show up no problem. I have a working Catalina system so I tried to boot the installer from the Catalina’s OC bootpicker. It shows up there, but after selecting it comes a few seconds of booting than a stop symbol shows up instead of the apple logo.

Where should I look for the problem? Should it be in the config or in kexts/drivers? (I made the installer USB with terminal, using the installer app that software update downloaded.)
