Google Maps becomes unresponsive after a few minutes

I have this peculiar problem:

When i use Google Maps in my browser, i can click around, search and zoom but after a few minutes Google Maps becomes unresponsive and just "hangs". The browser tab indicates that the page is loading. Sometimes the problem goes away after a few minutes, but in most cases i am forced to close the tab (or even the browser). If i then quickly open up a new tab and go to google maps it takes a while to load, and then i can use it for a few minutes and so on.
If i just open google maps without having it opened before in the current browser session, it loads instantly and i can use it for a few minutes, and then it hangs.

- It only happens with google maps.
- It happens with all my browsers: Firefox (standard), Chrome and Edge.
- It only happens on my PC, the other computers in our household does not have this problem (note: my pc is the only one connected by cable to a switch and then to the router, the others are on WiFi).
- Cleaning cookies, history and cache does not prevent/solve the problem.
- Everything is updated (and this problem was also there in v. 1909, so it's not a 2004 problem).

My sons PC has a similar configuration to mine: Same motherboard, same processor, same antivirus/internet security, same Windows, but different RAM and different graphics card, and he uses a WiFi USB dongle.
My ISP recently exchanged my router (the old one just stopped working), but i had this problem on the old router too, so it does not seem to be router-related.

Any suggestions or ideas to how i can troubleshoot this?

Thanks for your suggestions @dalchina

I realized that only my pc is affected and it is the only one that is connected by a LAN cable.
So i figured that before doing anything else, it would be best to check the wiring and connections. I had a new, spare LAN cable and connected my pc directly to the router, bypassing the 4-port switch.
Problem fixed!

I would never have guessed that the switch/wiring was the problem, as streaming, gaming and surfing all worked well.
I even did a download/upload test recently and it was all good.
How can this only affect google maps?

Nevertheless, problem seems to be fixed.

I'm off to buy some new cables and a new switch :)
