Ubuntu 20.04 Freezes randomly and media loops the last 1-2 seconds clip

After a few days of installation of Ubuntu 20.04 on my Desktop system, I am facing this issue of my OS freezing at random intervals. Happening 2-3 times a day.

The question may be similar to this one but the those answers are not applicable because I already have 16 GB of SWAP and a recent kernel version.

I also checked many other similar questions but could not find the specific solution.

The picture of the htop, the last time it happened.

I checked the /var/log/syslog file and could not find anything relevant.

Screenshot of syslog file.

All the time it froze, I was using two browsers: Firefox(2-3 tabs) and Chrome(4-5 tabs, youtube in on of them) and a few other applications like Vscode, Terminal etc. I was not doing any heavy(memory-wise) work.

I am not sure what is causing this. One possible culprit I am guessing is 'may be', the dconf-editor. The issue started the day I installed dconf-editor because I had to add Byobu to the favorites in the dock. So, I followed some of the steps from this answer. But it didn't work as expected and showed some weird results. So I reverted all the changes done to it.

Adding here the relevant system information.
