Keyboard unresponsive on start, solves by tapping bottom of computer

Hi,
I’m a lucky owner of a Macbook Pro 13” Mid 2012 with a recurring problem.
When I start my laptop it often starts up with an unresponsive keyboard and trackpad. The only button that works is the power button which turns off the computer if I hold it for a few seconds.
After years of troubleshooting this, I think I’ve found a pattern.
When the keyboard is unresponsive and I tap the bottom of the laptop quite hard in the middle, closer to the trackpad then the screen, of the bottom enclosure, the keyboard and trackpad starts to work again and I can log in to my computer, until I turn off the computer again.
Over the years I’ve upgraded the RAM, switched the hard drive to an SSD and changed the battery following the guides here on ifixit (thanks for those!).
Any help on what my current problem could be caused by?
All the best,
Malmoola

Here’s a couple of photos of the connectors for the trackpad and the keyboard after cleaning:
