This was supposed to be fixed in core as part of #16152 but maybe it requires a special change for custom reports as well. In #16152 (comment) it was mentioned that this was supposed to work for custom reports as well. Feel free to move this to custom reports issue project if needed.

Executed command:

./console customreports:archive --date=2022-03-01,today

We're still getting a failed archive email when a custom dimension is deleted:
