Sounds like a bummer with your new setup and especially in a tight apartment where noise echoes. I've fixed a few appliances over the years as a hobbyist and and grinding often points to misalignment or dry parts rubbing. Unplug and disassemble as much as the manual allows, inspect the drive coupler for any burrs or irregularities and a light lubrication with food-grade oil might help if it's accessible, but only if you're comfortable. Test it empty afterward. Works great sometimes.
If nothing changes,, contact support; defects happen. Keep us posted on how it goes.
In our family threads I post a pinned note that I mute chats and to @ me for urgent items. For exits I use one sentence, then leave or archive. Template is neutral and repeatable so no one takes it personally.
