So I went to put the beta on my Pixel 3 XL. After it downloaded my phone stayed on the Google logo for an hour. I could get into bootloader but when I restarted it did the same thing. My phone also didn't let me hard reset either. I went to do something on the computer and my phone loaded back up randomly and then said "Installation problem". Do I try to install again or stay away?

You can try installing the beta again. The worst that can happen is that the computer won't see the phone and you can't get the phone off the bootloader. If that happens, hold the power button in until the phone vibrates - it could take a minute. (You'll see the bootloader flashing on and off while you're holding the button in.) If that happens, go back to Pie. (Try it with the -w deleted from the last fastboot line first, to keep your apps and settings. If that causes problems, first try a cache clear (from recovery). If that doesn't help, flash the Pie ROM with the -w back in the last fastboot.
