I just spend a full day on migrating my Pb 2019 R3 build 2703 and our customers to 2797 for nothing.
Of all the bugs listed on https://www.appeon.com/standardsupport/bugfixes?contents=&product=PowerBuilder&category=&version=2019+R3&build=2797 the only one that could affect us, was the bug 7748 https://www.appeon.com/standardsupport/bugfixes/view?id=866.
[EDIT]
Turns out that that the bug does not exist on 2019. It's a 2021 bug. Please read Julie's answer: It only happens with specific builds of PB 2019 R3 and specific (older) versions of Windows 11. Information that could have been given along with the info on the bug fix.
regards.
