Cannot Package InDesign File from Synology NAS SMB Share

As mentioned in the thread referenced by @Abhishek Rao, it's a known issue on macOS Tahoe (which I assume you're running.)

Hello @Oguz5E8C,

I appreciate your detailed explanation of the situation. In addition to what the expert mentioned, could you please verify your operating system and the specific version of InDesign you are currently using? 

Furthermore, could you check if the issue you're experiencing aligns with what is outlined in this community thread:

You can usually blame the NAS rather than InDesign here. Packaging needs full local style read and write access and many SMB shares don’t let InDesign do the temporary copies it needs even when permissions look fine. The most reliable fix is to copy the INDD and its links to a local drive, package from there, then move the package back to the NAS. Mapping the share as a proper drive or remounting it with full credentials can help but working locally avoids the problem entirely.
