Can not wake up after sleep using 5.4.0-73-generic, but 5.4.0-65-generic works fine

[eries]

I'm having trouble waking up my computer which was previously in sleep mode.
I'm using a Dell Optiplex 5040 computer, an Intel Core i5 6400 with Kubuntu 20.04, and the linux kernel version-image-5.4.0-73-generic,
then I tried to switch to kernel version linux-image-5.4.0-65-generic and the problem was resolved.
I hope this problem can be resolved in the next kernel update.
