I used WinDBG to issolate a problem with Newer versions of Samsung Magician on my computer running Windows 11 25H2 fully updated. I tried all of the standard things - sfc and DISM - full uninstall and then delete of any samsung magician files in AppData locations, Program Files* , ProgramData. Then rebotted and clean install - did not fix the issue.
I setup a windows dump capture for Samsung magician - here is the dump file : https://www.dropbox.com/scl/fi/vv1tlzbumplrn0pi4wd8i/SamsungMagician.exe.14680.dmp?rlkey=du9hx3ch9w3oq8m9dknliz72c&st=u3stivbo&dl=0
