There's another thread, started more recently than this addressing this same issue. QB is a terrible program, the code was written by imbeciles and nothing we can do at this point will stop it from crashing despite all of their "help" in wasting our time uninstalling, reinstalling, running various "fixers". The problem has to do with the new browser Intuit has put into QB to allow them to send ads to us through the "discovery hub". In short, it's not you - it's them!
The only thing I have found that works to allow QB to run reliably now is to take my PC offline (by shutting off wifi) before opening it. After it is running you can turn wifi back on if you want and it still seems to work fine (most of the time I just leave it off while QB is open). Until their engineers get a chance to fix it (most of whom are probably on summer break from elementary school) it will not run reliably, so don't waste your time trying to fix yours. Eventually an update will be issued that will fix it (and probably cause a host of other problems).
I have been using QB for years and can say it is always the most unreliable, worst program. I have all my data on it so can't switch easily so pay them their "protection money" every few years when the make an older version obsolete but once my Desktop pro 2020 is no longer "supported" I will find another accounting package to use. I have wasted far too much time trying to use it over the years. I wish someone would start a class action lawsuit against Intuit so we could all get our money back for what is clearly a defective product.
