I had a similar issue recently and at some point realized it was because systemd started freezing all processes before suspend, and didn't always succeed (either with the freeze, or with the unfreezing after resume). Check your logs if you have a message "Freezing user space processes failed". You can disable this behaviour with the instructions at https://github.com/systemd/systemd/issues/33626#issuecomment-2209364985 https://github.com/systemd/systemd/issues/33626#issuecomment...
