Swap causing very slow boot (and systemd says the swap partition became active after 500k years)

I'm dualbooting Fedora Kinoite (ublue-nvidia image) with Windows 11 and I have a boot time of over 1 minute (only on the Fedora side).
The output of

Anyway, the
x2dadb07819a7b1UUID belongs to the swap partition.Output of

if you have enough RAM, you only really need swap if you want to hybernate. i'm running without swap for >10 years now. the only times regular users hit OOM is when a weird error happens and in that case you want it to be OOM killed quickly instead of your system becoming super slow while it tries to swap gigabytes of what the broken program is allocating.
Just because it's worked for you doesn't mean it's the best option.

It’s an odd situation anyway since Fedora has used zram swap for a while.
I might actually end up disabling swap in the end. I wanted to update that apparently I “fixed” the problem (not sure if permanently) by turning off the pc, unplugging the PSU, and holding down the power button for 30 seconds. Normal reboots weren’t enough. I’ll take it for now.
