ComputerSc/Technical domain question - how can i learn coding and other technical stuff when I can't visualize it?

I honestly don't know how to google this or find out if it's a specific issue with someone like me. I am very bad with technology, coding and concepts related. For more than a decade I've struggled to just remember the fundamentals and how they work but i do not understand the process. Lately I've realised thats because - I can't visualize these concepts so my brain does not grasp the explanation and promptly forgets them, out of sight out of mind.

On the contrary, the tangible stuff i can see and feel, I'm pretty good at troubleshooting, like I'm not only able to understand how to do but also remember tricks and techniques to apply in different problems but same doesn't work with technical stuff. Then I start feeling dumb and shut down and end up forgetting explanations faster. Its a never ending loop messing with professional life.

Has anyone overcome this? Or faced this? Or knows how to deal with this? Help me please!
