Mine was exactly the same. It was fine then I tried to download the Big Sur update. It says more than a day for a while and then failed. From that point I could not launch third party applications, the machine seemed slow, additional attempts to download the update would give a fail error, but apple applications would work just not great. After several reboots I was able to get third party applications working just enough to finish the work day.My machine can no longer run any 3rd party programs after a restart after several installation failed notices during download.
Things happen. IN fact Microsoft's problem a month or two ago was about this level of "bad". Our office was completely shut down due to it: https://www.datacenterdynamics.com/en/news/microsoft-outage-brings-down-azure-office-365-and-teams/Pathetic.
Netflix, etc, can handle the load when a new movie or TV series is dropped. You'd think Apple would've figured this out by now.
I took that comment to be a joke. Obviously it doesn't because nobody has an M1 machine yet. Also I've been running Big Sur Beta along along w/o any problems.my ass it does
Guys, please keep posting screenshots of the same error message, it's really interesting and helping.
A very Good Luck day. Love it!Friday 13th is tomorrow tho!
My install attempt looks like it downloads 90% of it, but the text says it all downloaded, 12.81 of 12.81. then the "Installation failed". I rebooted and tried it again, and yeah, the Installation failed comes up right away.
Apple this morning released macOS Big Sur to the public, and since the software went live, it has had extremely long download times that have prevented many from being able to install it.

Even those who have made progress through the download have run into problems where the software downloading process is suddenly interrupted and must be restarted. Others have reported being able to download the update and then having the installation fail. Apple's site appears to be having some major issues due to the number of people attempting to download the update at once.
In addition to these Big Sur download problems, Apple's developer site is also down at this time, and as a result, some third-party apps are unable to be opened up at this time.

An error occurred while installing the selected updates
It's not clear what's causing the problem. It could be that the macOS Big Sur downloads are failing due to a developer site issue or the developer site could be failing under the strain of macOS Big Sur demand, but it is clear that those hoping to get the new software should hold off until things are more stable.
Apple's System Status page is listing an issue with macOS Software Updates and says that the problem is "currently being investigated."
