The short version of the previous would be:
do you actually have an issue
or are you just concerned about some messages you saw? 
When my laptop pc restart or shutdown then i got this error message but laptop is running
My laptop is asus, corei5, 16gm ram. My running kernel is 5.18
**are you just concerned about some messages you saw? **
Just want to know about , anyone face this warning.
I googled this for you: “unknown filesystem efivars”
and the first hit was this thread here:
Manjaro boot error "mount: /sys/firmware/efi/efivars: unknown filesystem type 'efivarfs'
Perhaps it will help you - and/or perhaps you want to share some context and more information in order for others to be able to provide some insight.
I have checked already, I am waiting for next update. It was also happening in my office pc so i think this is new update issue.
Thank you for your help.
