Ubiquity installer crashes on secure-boot install lenovo thinkpad T14

[x10an14]

Trying to install with the combinations of encrypted drive, (zfs|ext4), and (with|without) secure boot.

I seem to be able to install both FS options without secure-boot.
I don't seem to be able to install either with secure boot as long as I install with the advanced feature (encrypted drive) enabled.

Ubiquity crashes at some point after the "select your timezone" screen appears (I have gotten further, but it's always crashed with the similar issues reported in syslog/dmesg).

```

This may be a duplicate of https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1976585 but our ubiquity outputs seem to differ (from what I can tell off the last ~50 lines).
