What I’ve Tried:tried different BIOS versions, kernel options and nvidia drivers.

Yes, I would agree.
New hardware often requires a recent kernel
Download an Ubuntu 24.04.3 ISO and try a live session
The kernel is linux-generic-hwe-24.04 6.14.0-27

Sir, The issue is our application works only on 22.04. Is there any way i can make it work with 22.04?

If it’s your application why don’t you update it to work with newer kernels? That’s always the saner approach.

Why didn’t you mention this application in your original post?

As mentioned by @celticwarrior , it would be sensible to contact the authors of this software.
Moreover, Ubuntu 26.04 LTS will be released in April 2026 - surely you would want this application to be upgraded for 26.04 and then enjoy 5 years of Long Term Support?

Do you have the latest BIOS?

There is version 03.05.03 Rev.A released on 2nd Jan 2026

I tried 3.4.2 as it was the firmware listed for Ubuntu OS

Thanks for the suggestion. We have already requested the authors of software to provide for higher version of Ubuntu. in the meanwhile, is there any solution that can help me overcome this issue?

It happens the newer version (recommended) is not packaged for Linux OSes (yet) but if you have the ability to install it - not that hard - anyway, you definitely should. Among other corrections it mentions Updates the Intel WiFi UEFI firmware to version 3.3.16.25315. Firmware is OS agnostic.

You may try installing a newer kernel. Experts here can tell you how. Keep in mind this may create other issues. There’s a reason each release is kept within the same main kernel version (except LTS where you have options.

Download an Ubuntu 24.04 ISO
Test a live session for a few hours
If you’re happy, install to your disk
Create an Ubuntu 22.04 Virtual Machine using qemu/kvm
Install your application in the VM

Just a guess, really, because we don’t know anything about your application
