Critical Bug: Objects inside Symbol shift out of place when moved with Selection Tool (Cannot Undo)

Hi everyone,
I am experiencing a critical bug with the Symbol feature in Illustrator and wanted to report it.
My Workflow: I am designing packaging cards that share the exact same layout but have slightly different content. To do this efficiently, I use Symbols that contain multiple objects.
The Issue: After placing a Symbol on the artboard, when I move it using the Selection Tool (the black arrow)
, the positional relationship of the multiple objects inside that Symbol completely breaks. The objects shift to unintended positions, destroying the layout. Additionally, this layout corruption cannot be undone using the Undo command (Cmd+Z / Ctrl+Z).
Temporary Workarounds I Found:
Replacing the Symbol: Select a different symbol temporarily, and then switch back to the original symbol. This restores the correct layout.
Avoiding Symbols entirely: Stop using the Symbol feature and expand everything, which defeats the purpose of my workflow.
Finding and correcting these broken layouts manually by eye is extremely difficult and time-consuming. I hope Adobe acknowledges this critical bug and releases a fix soon.
Is anyone else experiencing this issue?
My Environment:
Illustrator Version: [30.6]
OS: [macOS Tahoe]
