Hi Ashraful Islam,
We're hoping you made a backup copy of your /etc/fstab
You will probably have to boot into a rescue mode using a RHEL 8 install ISO. Some instructions are here https://access.redhat.com/solutions/770703.
We are not exactly clear what edits you performed on your /etc/fstab and without being there in person, you would be our eyes and ears.
Are you able to reload the system? Is it a problem if you were to reload the system?
If your system has important data, you may have to do a rescue operation using boot media described in the article above.
This may be complicative over a discussion here, and you can certainly submit a case with Red Hat too.
Kind Regards,
RJ

Hi Ashraful Islam,
I myself am busy with some things, if another volunteer doesn't get to you , consider opening a case with Red Hat.

XFS has ACL enabled by default. You do not need that option in /etc/fstab and it can cause problems during boot. You would need to boot from a recovery image and fix /etc/fstab. Also, you listed the entry for / as dev/mapper/rhel-root / xfs defaults,acl 0 0 The line should start with a '/' (/dev/mapper/...)
