Hello, There was a diff and conflict between DevelNUI and main, causing difficulties in integrating NUI. Therefore, a hard reset was performed on DevelNUI. As a result, the pull requests (https://github.com/Samsung/TizenFX/pulls) in DevelNUI are now conflicting. To resolve this, you can go to the specific PR, where you will see an error indicating a conflict. You can then use the command line to resolve the conflict.
or Here is another example. This one updates everything below the topmost patch, leaving only the topmost patch unchanged.

git fetch upstream  
git rebase --onto=upstream/DevelNUI HEAD~1  
git push {current working branch} -f

I'm sorry for the inconvenience.
thank you.
