QBO App for Windows suddenly very buggy

Agree - having the same issues.  It is so frustrating that Intuit has such terrible issues with core service offerings.  If they aren't going to support the QBO desktop app, or make the functionality work consistently, then they should just abandon it and tell users as such.  Instead, they appear to have no actual product management, use junior developers to make updates, perform no testing, provide no outreach about problems that are obviously occurring for multiple users, etc.  This Company has a market capitalization of $168B, and they can't even support one of their two core products.  It is so frustrating that they use their lack of competition as an excuse to spend as little as possible to actually make their products useful for users.

This little message now pops up every time the app fails to open, which, since yesterday, is now often.

Receiving pop-ups every time you open the app can be quite a hassle, Mario. It seems like it needs a closer look. I recommend contacting our live support team directly. They have specialized tools and gather data to investigate and get you a quick resolution. I'll guide you on how to reach them.

If you are here to help us, please get in contact with your development team internally and tell them they need to investigate why so many users are submitting complaints about the QBO desktop app being buggy and no longer working properly.  You and they can read all of the posts and comments that have been submitted to get an understanding of the issues here.  It's unnecessary for users to take up more of their time to explain things they have already explained, that are most likely traceable back to something that the developers would have a log of.  Intuit developers should now what new code/functions/features have been recently released and should be able to reverse engineer what is causing these issues based on their recent code base updates/releases.  Intuit/QBO customer support needs to do better.  The patronizing "non-helpful" response below is not what users want.  What we want is a support team that takes ownership of the messes that the development team creates and actually has a process to relay these concerns internally to developers so that the development team can fixes what they broke.  This shouldn't be that difficult for a company that is worth over $150 Billion.
