Fix Functionality Errors in .NET Application

My .NET application is experiencing some bugs that need fixing. The issues primarily revolve around functionality errors with user input forms. I need a skilled developer to diagnose and repair these issues promptly. This will need to be done using screen share as we cannot give access to the code/server, only freelancers who can work over screen share, guiding me step by step should apply

Ideal Skills and Experience:
- Proficient in .NET application development and debugging.
- Extensive experience in troubleshooting functionality errors.
- Familiar with user input form assessments and repairs.
- Able to deliver fixes in a timely manner.
