hi Chris, I reproduced the issue
Volo.Abp.AspNetCore.Mvc.UI.Theme.Shared.Demo
project is missing on NuGet. We'll add this in v3.3.0
See the commit for that https://github.com/abpframework/abp/commit/0242db8d076e889513f95a293d48857a9a120fd6
Not to block you now, I'm sending the related DLL https://drive.google.com/file/d/1i8MvNX2kVAeeOIgPwAsQ5vTLy1_Udszb/view?usp=sharing
yes this might be the issue
normally this problem will not happe in your production environment. we as developers often recreate database, delete tenants etc. that's why we face this problem.
yes, if you change the database provider, you need to remove all migrations and add again, because each DBMS has its own data limitations. please read https://docs.abp.io/en/abp/latest/Entity-Framework-Core-Other-DBMS
