Keyboard and trackpad stopped working but work with Ubuntu

Hi, last day I switched on my MacBook air and all of a sudden the trackpad and keyboard did not work anymore, however, the power button worked fine.

After reading many forums this is what I tried:

I did reset many time NVRAM and SMC (note that the keyboard would function when used to reset)
I did a new installation of OS (a tried with Big Sur, High Sierra and Yosemite) and did not work.
I used ubuntu live to completely erase the SD and install again the OS
Tried all tips found online, like removing .plist files etc

Then to be sure that was not a hardware issue I opened the MacBook and looked at the cables connecting the keyboard and board, and it was just fine (no water damages)

Out of frustration, I installed Ubuntu and the keyboard and trackpad are perfectly working.

Any idea of what is going on?

The issue seems to have appeared after upgrading to Big Sur

Thx :)

MacBook Air 11″, macOS 11.4

I believe I had the same problem. First I had fan issues, then the keyboard issues. I went to the apple store, I did multiple recoveries, both clean and backups. With he same problem reoccurring. My solution is on this thread here https://discussions.apple.com/thread/252950157, with multiple other threads listed at the bottom with people with the same problem. I know it sounds dumb, but it worked for me.
