There was an issue when synchronizing with the third-party application

I used a software called 'Remotely Save' to achieve multi-device synchronization of notes via OneDrive. It creates a folder named 'remotely-save' in the Apps folder on OneDrive and uploads files there. However, after using it for eleven months, I recently discovered that this folder was automatically set to shared. So, I deleted the folder and resynchronized, but the new sync folder was renamed from 'remotely-save' to 'Graph'. Additionally, the folder was still set to shared upon creation, as shown in the image below.

Afterward, I tried deleting the folder and syncing again, but the issue remained unchanged. Finally, I switched to a different OneDrive account for synchronization and found that the synchronization on that account worked normally. The sync folder is shown in the image below.

The folder name is normal, and it is not set to shared. The old OneDrive account was the same before, but it seems that changing to the 'Graph' folder is an irreversible process. After it changed to the 'Graph' folder, the synchronization time also doubled. Therefore, I would like to seek your help to resolve this issue. Thank you!
