It does sound odd, but there are reports that installing Nvidia drivers prevents the drivers for things like network adaptors and touchpad s getting loaded.
Seemingly credible suggested fixes involve experimenting with different linux kernels.
I don't know if that is something you'd want to do, if not, then stick with the provided drivers.
Edit - Test method added to post
To check if this is what's happening, from a fresh install, do all the updates except the Nvidia drivers.
Using Timeshift may stop you needing to reinstall.
Use Timeshift to create a system image and give it a label.
Check the network works, then open a terminal and run the following command.
Copy the terminal output including all the results and paste it into this topic.
Then do your Nvidia changes.
After rebooting to a failed system, repeat the command above and copy the terminal output to a file.
Use Timeshift to restore your system to the image you saved earlier. This should restore your network.
If so, paste the contents of the file you made while the network was down into this topic.
