Big Sur not opening Applications even after 2 Reinstalls

I have installed and reinstalled Big Sur 3 times now but it still refuses to open Applications without crashing out first. I want to know why. These are applications that have opened without problem on Mojave and Catalina. I can see lots of answers but none of them seem to have worked and all of them require me to use programming instructions of some kind. Why can't YOU (Apple) get this sorted out for ordinary users like me who just want to use their Macs without hassle?

This is the developer forum. All answers will require you to use programming instructions of some kind. That's the whole point.

You should probably post your question in Apple's Consumer support forums instead: https://discussions.apple.com/welcome

Those consumer support forums are much, much larger. Instead of waiting days (or forever) for an answer, you can expect an answer in a few minutes. You just have to make sure to pick the appropriate forum and provide a good description of the problem. Sometimes, the big forums are so busy that questions don't get answered in a few minutes and they fall off onto page 2, where no one will ever look for them. After 24 hours, an Apple Community Specialist will offer you a couple of Apple Support articles that might or might not help.
