I was unable to update to big sur

When I install, it seems to be fine, I tried to update but it never successfully went through. It went completely black, like shut off. When I powered on it would show the apple logo for less than 10 secs then go completely black. The only resolution was to put it in recovery and then use the previous os system. Am I going to be able to update to Big Sur? What is going on? apple support was not helpful

iMac 27″, macOS 10.14
