Sorry, the OpenIddictDataSeeder file I sent in the previous email was one that I had already modified myself, so it didn’t contain _configuration.
I have created a new project and I’m currently experiencing the same error. I will send you the new OpenIddictDataSeeder file from the fresh project. Below is the output I got after running the dotnet build command as you requested.
[maliming] said: BWT, what is your CLI and Suite version?
dotnet tool list -g
I have checked the CLI and Suite versions according to your instructions, and here are the results:
volo.abp.studio.cli 2.0.2 abp volo.abp.suite 10.0.0 abp-suite

Please help me fix this issue so that I can continue using ABP Suite for the remaining features.
