Sometimes there will be some bugs in the software, which is inevitable. My suggestion is:
① After uninstalling the software, reinstall it once to see if there will be such a problem;
② In addition, you can also try to install the software on a disk other than the C disk. Because of the configuration, sometimes the software can't get the answers stored on other disks, which leads to the software scoring error.
③ Carefully check the installation path to ensure that there are no errors.
If you have any questions, please ask.
