Ok so I was wrong (thank you Ivan) and you have indeed an international model.
I'd say, if you're positive that you have follow the right order for flash, that it could be the famous "install TWRP app " issue. You have to uncheck the "install TWRP app " box after flashing the ROM.
If you use magisk, you have to flash ROM and Gapps, boot and configure the phone, and then flash magisk.
If it's not one of this known issue, I have no idea.
Bro thanks but I have tried it also !
I only installed the rom and the twrp app option is unchecked
