Here also a similar issue and easy reproducible. I am using an M1 Mac Mini with an external Samsung 980 Pro 2TB NVMe in a USB-C enclosure (https://www.amazon.com/Hagibis-Enclosure-MC25-Pro-DP/dp/B096LMGTNG). Copying files larger than 20 GB will cause the disk to eject. Just now wanted to create a backup from SD-card to this external HDD, the backup worked until the image reached the size of 21,06 GB (21.048.066.560 bytes). This is really frustrating, as I bought for 400 euros worth of hardware and can't even use it in a normal way. I tried several connection options and found that connecting the enclosure using a USB-C to USB-A (USB 2.0) cable resolves this issue of copying large files. But the overall speed is extremely slow in comparison. Hope this can be resolved eventually in the OS software and it is not hardware related.

We are having the same issue. We are unable to find where to configure this shown entity name in the invitation.
