Application randomly crashing

Question

This is my PC at work. It is Dell Precision 3630 Tower Workstation. When we purchased it, it initially came with one 256 gb ssd + 1 tb hd. I had Kubuntu 18.04 installed on it with root on the ssd and /home on the HD.

The issue I am having is basically any application I have open, there is like 20% chance for it to crash every 20 min. I use mostly Visual Studio Code (VS code) on it and literally every 20-40 min, the editor stops responding and I have to wait until it says to reopen or exit (I don't lose any files/unsaved data in this program). I believe VS code spawns multiple processes and only one process crashes since I can still click on the menubar. Also, different windows don't crash. It is just anything inside the crashed window is not responding.

This issue is not exclusive to VS code, Google Chrome and other work applications crash and disappear completely. In addition, a notification shows up every once in a while saying Ethernet connection disconnected then reconnected 1 sec after. No internet is lost.

I thought the issue might be with KDE plasma 5 (since this was the first time I use it), so I installed Gnome and the issue was the same. Also note that I have 32GB RAM on this PC (with 4GB swap) so running out of memory is never an issue.

I did the following and all of them failed (mostly hardware):

I installed a newer kernel (5.7) and still same issue.
I removed the ssd and hd and installed a new 1tb ssd and installed Kubuntu 20.04 from scratch on it (root and /home in same partition). Same issue.
I did a memory test using memtest86 (https://www.memtest86.com/). No issues in 2 hour run (Also tested again in diagnostic tools)
There is a Built-in self test (BIST) with the PSU. I tested it. No issues.
I ran the diagnostic tools that comes in the BIOS. It tests CPU/GPU/memory/network card/HD/PCIe bus/cables/fans with different stress tests. No issues.

The PC is reported to support Linux (We bought it with Ubuntu 18.04 preinstalled). I also have latest BIOS firmware for this PC (reset it too) and latest firmware for the new SSD (1TB Samsung 860 EVO).

I am not sure what is causing this issue and I tried almost everything with no hint on the cause. Any suggestion on how to fix this issue. Below is link to logs from /var/log/syslog for 1 hour where VS code crashed once and the LAN connection restarted twice (changed name/ip for privacy reason)

Edit: VS Code crashed 5 minutes ago. Here is the output of journalctl in the past 5 min.

I contacted Dell and they sent me a replacement motherboard with cpu. I thought they will take ages to send me what I need but they were very fast (aka next day they shipped them). I guess if you buy from the business division, you get better service.

I installed the replacements and the issue has be fixed. I guess the motherboard or the cpu have to be the issues. I am still having the other issues with the network card restarting but I believe this issue is unrelated and has to do with our corporate network.

Also, special thanks to @heynnema for helping me go through the debugging steps. It helped me narrow down the issue.
