I followed the below steps and recovered the system successfully.

1. --->> Steps remove the libcrypto.so.1.0.2k.

[root@linux2 ~]# cd /usr/lib64/
[root@linux2 lib64]# ls -ltr | grep libcrypto.so.1.0.2k
-rwxr-xr-x. 1 root root 2521008 Apr 9 2019 libcrypto.so.1.0.2k
lrwxrwxrwx. 1 root root 19 Aug 14 13:55 libcrypto.so.10 -> libcrypto.so.1.0.2k
[root@linux2 lib64]# rm -rf libcrypto.so.1.0.2k
[root@linux2 lib64]#reboot

1. During bootup, when the GRUB2 menu shows up, press the e key for edit.

2. Add the following parameter at the end of the linux16 line on x86-64 systems, or the linuxefi line on UEFI systems:

systemd.unit=emergency.target

As the Below Screenshot shows.

Will the rescue mode using the installation DVD help you with the problem?

Chapter 32. Basic System Recovery
32.2. Anaconda Rescue Mode

The rescue mode can mount your system's rootfs. Also it can mount an external USB stick. So then you may copy the proper library file from other healthy system to the broken rootfs via a USB stick.

The attached screenshot may show you how it works. I have only RHEL9 system on my desk, but the steps would be almost identical even to RHEL7.

The rescue mode mounted the rootfs of the target RHEL9 system under /mnt/sysroot. And then I mounted a USB stick '/dev/sdb' on /mnt/usb which contains the library file. Then it should be possible to copy the healthy library file from the USB to rootfs, although I did not actually run the copy operation since I was afraid of leading any negative effect to my working system.

Hello @Ksahil !

Agree with @tnishiok here !

Once you are  booted into live environment , you can then reinstall "openssl" package  which provides the libcrypto.so.1.0.2k file :
