Serious issues after installation on Motorola G32

/e/ version: 2.4 (but tried also with 2.2, 2.3 and 1.21) devon
Device model(s): Motorola G32 XT2235-2
Developer mode enabled: yes
Device rooted: N/A
Trackers blocker enabled: N/A

Summary

Power and volume buttons not working; crash after a bunch of seconds, reboot with only power off or reboot functionalities working.

The problem

Steps to reproduce

What is the current behavior?

After having flashed dbto, vendor boot, recovery img in fastboot mode, sideloaded e/os in recovery mode and rebooted the system, the welcome screen appears, but the power and the volume buttons are not working. After some seconds (40-60) the system crashes and reboots on a dark screen; at this stage th the power button works back allowing to reboot or power off - no other action is possible. After the reboot, the issue repeats: the system works for 40-60 seconds (power or volume buttons keep not working), then crash, reboot, dark screen allowing to power off.

I have also tried to flash original LineageOS dbto, vendor boot, recovery img in fastboot mode (kept E/os 2.4) and, after the restart, the system turned more stable, all the buttons worked, no crashes happened, but connectivity was completely cut off - both wifi and mobile network were not available, and placing calls was not possibile

What is the expected correct behavior?

Power and volume buttons should work, no crash and reboot should happen; on the other side wifi and cellular connections should be available.
