If the previous flush installation and unloading indicators are normal, then the biggest possibility is that the calculation of an import formula is too large, resulting in the software being dead (stuck).

Uninstalling, reinstalling software and deleting indicators can't be solved. It is recommended to change the installation directory during reinstallation to avoid duplication with the previous installation location. This can prevent the pointing of the remaining data from causing the same failure.

If the installation location cannot be repaired by changing, it is likely to be a software conflict or other system and registry failures. These failures are difficult to eliminate, so we have to reinstall the system.
