[SOLVED] dm-crypt: "cryptsetup open" hangs during Arch setup

I'm setting up Arch on a Dell XPS 16 and am having trouble encrypting the hard drive. Specifically, I'm following the instructions in dm-crypt/Encrypting an entire system: LUKS on a partition with TPM2 and Secure Boot and every time I run "cryptsetup open" the prompt hangs, requiring a hard reset. This happens both when using dm-crypt to secure erase the drive and after creating a LUKS volume for the root partition. In the latter case, it hangs after the password is entered.

Someone had a similar issue in 2020, but the issue was never resolved and the problematic kernel modules mentioned there are not present in my setup. I tried using the "cryptsetup --debug --verbose ..." but this gave no insight into the issue. The only other lead I have is that the "dm_crypt" kernel module isn't loaded in Arch live. I tried loading it with "modprobe dm_crypt" and the prompt hung, requiring a hard reset.

Let me know if I'm doing something wrong or if you have ideas on what else I should try. Thanks!

It turns out this is some kind of issue with the current release of Arch (2025.05.01). I verified the ISO signature when I downloaded it and flashed it to the USB multiple times using dd but the problem persisted.

Downloading an older release (2025.03.01) fixed the issue!
