Just my 2 cents:
2020.11 has been running fine here. I have had zero crashes. Sometimes, certain plugins take a bit to open(Ozone 9 and Melodyne), but that's actually par for the course with those 2.
Regarding worrying about updating, caution is a good thing. But, its easy to have a backup plan. If you have a desktop PC, I would get SATA drive cage(at least a single slot model) and buy a second hard drive(preferably an SSD) of the same capacity, and clone your current system drive. Then, install the cloned drive and update that one. Start by uninstalling Pro Tools(and the HD driver if that option appears) and then install the latest version. At the very least, use some drive imaging software and save an image of your system drive to any external drive(I keep a 6TB USB3 drive for backups and drive images, in addition to the 2 SSD's I rotate for each update)
FWIW, re using the Run as Admin command for installing and running PT, I stopped doing that a year ago and things have been running fine ever since. Also, if you haven't trashed Prefs lately, I would open Prefs and take notes on your settings(unless you have them memorized like me
) and open IO Setup and Export(save) the settings. Then when you do the uninstall, clikc the last option to also remove prefs, database files and everything else. The reset after installing the new version(its good to clean out the dust and cobwebs now and then).
Last thing: 2020.11 will default to DARK mode. Try that and see if you like it. As for me, so far, I am not a fan but its easy to open Prefs to the first tab and select Classic mode, then restart(Classic mode looks like you are used to seeing everything)
