Sorry I am not open to providing my tax information even in a diagnostic format. It is simple to recreate. Just have hundreds, like 500 stock transactions listed in Schedule D and it will happen. You should be able to copy and paste a bunch of fake transactions. Most people don't actively trade and only have a few thus why the majority of your customers don't see it. I actively trade stocks. I have also used Turbotax for as long as I can remember, back in the 90's and never had a problem and have always had hundreds of stock transactions. This is a bug that came out in the 2022 edition. Someone else might be open to sharing their return but for now I will live with the 10 second delay on each menu item while your code parses Schedule D and forgets to periodically yield so the GUI gets serviced. I write commercial Windows software for a living as well so am sure that is the problem.
