Im an IT consultant and I'd say about half of my customers that use QB2022 Plus are getting this crashing issue (about 8 different businesses at different locations) so it is definitely an issue with R5 and not a lone case situation. One of them though got a yellow warning about a HTMLHelper Module, which caused a "Quickbooks Unrecoverable Error" (none of the other customers gave me an error, they just crashed and closed all apps that were open at the moment), so I had to quickly click on it before the error showed up and Run the add-on. That at least stopped the Unrecoverable Error message; but it makes me think this is all caused by the proprietary browser Intuit is using to replace Internet Explorer 11. 

I would recommend you hurry up with a fix, most of my customers are talking about migrating to different software.
