Samsung Magician 7.2.0 writes "log.txt" to disk root on every login

I recently updated Magician to 7.2.0 and its Migration Service started creating text log on my secondary SSD root every time I start Windows. The file is named "log.txt" and contains some partition data. Using Windows audit functionality, I gathered the info about the process that creates the file:

Does anybody else have this problem and any workaround? How to report the error to Samsung Directly?

I'm using the latest Windows 11 build.

I just experienced the same problem on Windows 10. For anyone ending up here, I researched and found the "MigrationService.exe" program is initiated by a service named "CMigrationService". Open up Services and find CMigrationService. It will be running and can't be stopped due to the buttons being greyed out. capture1.JPG

 But you can still change the Startup type from "Automatic" to "Manual". Do that, click OK and then shut down your computer and restart it. The service will no longer run every boot nor create the log.txt file every time. Worked for me in Windows 10. This hopefully will do the same for Windows 11. If you ever need to migrate your Samsung SSD to another one, I assume this service will need to be changed back to "Automatic" until the migration is completed.
