I'm stuck in a bootloop. I would like to specify that I ran the twrp checked if I was able to flash something but I saw that I was not able to flash anything because my phone doesn't have the root I rebooted the phone, and from that moment I cannot run the os at all. I'm able to go to the fastboot and I'm able to run the twrp and the recovery.
I tried to reflash the boot only but without success. At this moment I tried to reinstall all the system 10.0.9 but I received this message:

Unfortunately, all these attempts failed. In the past, I tried the rooting. After the first period, it worked properly but I was not able to re-install magisk boot file as it was not recognized by the magisk app. I don't remember if there were some magisk module.
I don't know if this helps, please assist. If the topic is in the wrong section, please move it.
Thank you in advance for your help.

Try to install again the rom, and when the device reboot itself in recovery don't reboot it

thanks so much for your reply.
I realized that with the twrp I selected the partition A and I reinstalled the rom again and the system restarted. Now I'll try to restore the partition B. (But in meantime I'm performing a backup all the data ).
Update: I reinstalled the system in the Partition B and works properly.

thanks so much for your reply. I followed your advice and actually helps.

Update: I reinstalled the system in Partition B and works properly.
Update 2: I finally spend a bit of time on the phone and I already rooted. Thanks to @mauronofrio for help.
