Ubuntu 21.04 on Framework won't resume from standby. I have to force-shutdown with a power-button long-press each time. I haven't tried an A/B test, but I read that this behavior is due to the volume being LUKS-encrypted. I don't understand why this would be the case. Not encrypting the volume isn't an option for me.
