Whilst dealing with Problems caused by resume from sleep I thought I’d work around the problem by editing /etc/systemd/logind.conf to set it to ignore the laptop’s lid being closed. After doing this and restarting systemd-logind the system needed rebooting.
But, at that point, after going through the GRUB menu’s kernel selection the LUKS disk timed out; a password prompt never appeaed and I ended up at a rescue prompt.
I’ve tried booting from a live USB but can’t see the relevant disk in order to try decrypting and viewing it. lsblk shows this:

zram0 252:0 0 8G 0 disk [SWAP]
There should be a 500GB NVMe disk present.
I’ve tried using cryptsetup luksOpen on the /dev/sda* partitions but it reports that they’re not valid LUKS devices.
Presumably, as the GRUB menu appears and the system starts booting it’s not a complete failure of the NVMe disk. But, at this point I am rather perplexed and would welcome any suggestions.
