cryptsetup: waiting for encrypted source device /swapfile

I know this has been asked but I am asking this because the fix i found didnt work.I got the same problem this person had: https://www.reddit.com/r/linuxquestions/comments/cerr1l/ubuntu_1904_waiting_for_encrypted_source_device/

but i tried the fix which was to add "size=256" in /etc/crypttab.I did that, but it still warns me that I haven't specified size in crypttab and still takes time to boot. (my computer will still boot to a working gui if i type exit at the prompt)

Here's the contents of /etc/fstab:

# /etc/fstab: static file system information.## Use 'blkid' to print the universally unique identifier for a# device; this may be used with UUID= as a more robust way to name devices# that works even if disks are added and removed. See fstab(5).## <file system> <mount point>   <type>  <options>       <dump>  <pass># / was on /dev/nvme0n1p2 during installationUUID=694b4858-ead8-400d-9406-f9fc45dc71f1 /               ext4    errors=remount-ro 0       1# /boot/efi was on /dev/nvme0n1p1 during installationUUID=CA5F-286C  /boot/efi       vfat    umask=0077      0       1#/swapfile none            swap    sw              0       0#/dev/mapper/cryptswap1 none swap sw 0 0#/swapfile swap swap defaults 0 0/dev/mapper/cryptswap1 none swap sw,pri=100 0 0

and here is /etc/crypttab:

# <target name> <source device>     <key file>  <options>cryptswap1 /swapfile /dev/urandom swap,offset=1024,cipher=aes-xts-plain64,size=256

does it help that it worked all the time before but just doesnt now, and that i had to use Ubuntu recovery mode DPKG before I edited /etc/crypttab?

Any help would be VERY appreciated. TY in advance!

edit: it would be nice if i could keep swap as i only have 5.7gb ram (2.3gb ram is system reserved)
