Abaqus error: abaqs/ CAE kernel exited with an error
Hello, I am a user of Abaqus 2021 version. If the following error appears in the student version and cannot be used, the situation is as follows even after reinstalling.
I need to practice because I have to write a thesis, but I don't know how to fix it. I would really appreciate your help. The python version is 3.9. higher than 2.7. Also, I'm using an admin account. Any help would be greatly appreciated.
