Experts on the Ansys Innovation Space and FEAtips recommend trying these solutions in order: : Close all Ansys applications.
Introduction The ANSYS Workbench executable (ansyswbuexe) is the graphical front end that coordinates project files, launches solvers and tools, and manages the Workbench process. When it crashes or aborts unexpectedly, modern versions present a generic dialog indicating an error and that a diagnostic file was written (often to a temporary or Workbench folder). Because the message is terse, users need a structured approach to diagnose and resolve root causes that range from corrupted user files and license/server issues to GPU/driver conflicts and OS-level permission or antivirus interference.

Check if your antivirus has quarantined any files in the Ansys installation folder. Add an exclusion for C:\Program Files\ANSYS Inc . 5. Re-registering .NET Framework Experts on the Ansys Innovation Space and FEAtips
: Outdated or conflicting dynamic link libraries left behind by legacy third-party CAD applications can interfere with proper operations.
Understanding why AnsysWBU.exe fails helps narrow down the solution quickly:
The ansyswbuexe process is the core executable for the ANSYS Workbench user interface. When it crashes and generates a diagnostic file, it usually means there is a conflict between the software and your system environment, hardware drivers, or corrupted temporary data. 1. Clear Your AppData (The "Soft Reset") Because the message is terse, users need a
