Hello Ariel Kotulski

I will need more information to understand the issue.

When are you getting this error? Do you get this while opening the model? Are you getting it for a specific file, or for all files? Is it occurring when you perform a certain action? Have you ever faced this issue before?

Working on the same model in Ansys Aim 2020 R2 error occurs

 Were you working on this model previously and it was not giving the error, or you have worked on this model in some other version of  AIM?

Will it be possible for you to share the run files to me, I can look into it and see what could the issue be.
