i found out that Affinity Photo on Windows 1903 ( and maybe other versions of Windows 10 too ) immediately crashes/closes when attempting to start Affinity Photo. somehow i got the bright idea to disable the display of hardware statistics provided by RivaTunerStatisticsServer. i did that by opening RivaTunerStatisticsServer, adding Photo.exe ( the executable file for Affinity Photo ) to application profile list of RivaTunerStatisticsServer. then i set "Application detection level" to NONE.
i am posting this message to make sure other people will come across this whilst looking for the cause of Affinity Photo immediately crashing/closing.
and it would be nice if the developers are able to do something about this issue.
