I think you should boot in "verbose" mode which will, hopefully, give you a screen of scrolling text during the boot process and stop where the problem likely is. You can photo this and attach it to a post.

To do this either add a "-v" boot argument to the NVRAM line starting with 7*** in your config.plist, or press the CMD+V keys when at the boot picker menu, then select your boot option.

Well I have a feeling the "Little Snitch" app you have installed might be a stumbling block. There are known issues when updating macOS to the latest.

Can you still boot Catalina and disable it?

 

[CatTonyWoman]

Ok. I'll try this and let you know.

Is your BIOS set up as described in post #1? Is CFG lock disabled?

 

[CatTonyWoman]

CFG lock is disabled, and I modify my BIOS set up as post #1.
Better but not ok.
I've the Apple logo page + progress bar, progression then black screen

Did you add "agdpmod=pikera" to boot-args?

Can I add it with OC configurator ? Or do I need another soft ?
