Thank you for your help, alven.
I have already tried the kernel 6.2 as well. Unfortunately, it has the exact same problems.
I have given up on this notebook already. It is simply not suitable for Linux. I have looked on eBay and it is currently being offered for a higher price than what I paid for it new. I have just ordered a Tuxedo notebook and will be listing my LG for sale on eBay. With the Tuxedo, I know what I am getting and will not have these problems anymore.
