Issues with Disk Encryption and Network Resolution After Booting

Hello,

I recently installed Arch Linux using EndeavourOS with the KDE environment. During the installation, I opted to encrypt the disk and enabled autologin. However, I am encountering some issues every time I reboot:

I am prompted to enter the decryption password at boot. If I mistype the password even once, and then enter it correctly the second time, the system still boots, but I notice that:
The network is not available.
The screen resolution is messed up (and possibly other issues).

Occasionally, I am sent to an emergency prompt after mistyping the password, even if I enter it correctly the second time. When this happens, I decline the prompt using Ctrl+D and manage to log into the system, but I still face the same issues with the network and resolution.

I am looking for guidance on the following:

What could be causing these issues?

Thank you!
