I am looking for a bug researcher for a pc application

I am looking for a bug researcher to help resolve issues with a PC application. The specific issue that needs to be resolved is related to functionality errors. I'm not sure if I have any documentation or error logs related to the issue, but I'm open to suggestions. The programming language used for the application is Java. I'm looking for an experienced bug researcher who can quickly identify and fix the issues I'm having. If you think you have the right skills, please send me a proposal.
