Encountered error while editing photo using Paint Shop Pro

I was using Paint Shop Pro Photo to edit my photo images when randomly I got this error message (please see below).
I was editing and saving a photo when the error happened. I knew it was the correct file but I wasn’t sure about the permissions.
I hope someone from this forum can help me solve the problem.
Thanks in advance.
