Big Sur and brother label printer
When I installed Big Sur, I also had to replace my brother label printer. My new QL-810W was supposed to be compatible with the new system. It is, but the p-touch editor which is necessary to design and save labels crashes when I make any selection on the opening screen. So I went to a preferences page and directed it not to open that page and now it simply crashes when launched. I spent an hour on the phone with brother and they finally said to contact Apple. I wonder if the Ap Store copy version was updated slightly but not on the store. The version is 5.3.2 (558). The technician was sure that they had tested it and it ran.
