Internal error when loading solution in "abp suite" cli #4382

Hello, I am receiving an error when attempting to add an ABP 7.0 solution to "abp suite" for crud generation. The error is ""An internal error occurred during your request!" and it is received immediately upon "Add an existing solution" OR when selecting the 7.0 solution (once added).

Please note that the only enum in the entire application referencing "Medical" is this class: namespace Redacted { public enum ConditionType { Medical, Behavioral } } Note: I have not assigned a database/datasource in "abp suite". The error occurs on the initial load.

What would cause this type of serialization error? Is there a cache / directory that I should try removing?

Please advise.

• ABP Framework version: v7.0.0
• UI type: MVC
• DB provider: EF Core
• Tiered (MVC) or Identity Server Separated (Angular): no
