Had the same problem with mine. You need to change the sleep mode. You need to change sleep to mem_sleep_default=deep

I found it much more difficult. I had to move my swap partition into the LUKS partition so it was encrypted, resize it to be much bigger than the default then figure our how to have the RESUME=disk-uuid boot flag enabled for EFI boot. I got it working but it was quite time consuming.

This was the method I found but it didn’t work for me and I gave up.
