'Visual Studio 2019 or 2022 IDE don't save new bookmarks of project created in earlier IDEs

I developed a project in visual studio 2012 year ago but migrated to visual studio 2019. However, the bookmarks and the files opened won't save in the newer IDE. I have tried database and environment data clean up, cleaned solution and built, but it won't work. I have asked at least two times on Microsoft forum, now migrated elsewhere, to no avail. Any help?
