Hello and welcome to the formum. I am not very good at solving errors like that. But I know the people that can help will want a little more information, and you can read about how to provide that info in this link here: How to provide good information
At the bottom of the log I see this:
optimus_manager.kernel.KernelSetupError: module nvidia is not available for current kernel. Is the corresponding package installed
so you can at least check if Nvidia is properly installed, to do that, open up a terminal and put in
pamac list | grep nv
That should get people with more knowledge than I do with a place where to start solving your issue.
