AnsysWBU.exe encountered a problem. A diagnostic file has been written
I've been working with Ansys Workbench, Mechanical and Fluent for two weeks now and had no problems until today. When I opened Workbench, created a new Transient Structural window and tried to create a new DesignModeler geometry, DesignModeler didn't open correctly and gave me the error: "AnsysWBU.exe encountered a problem. A diagnostic file has been written: C:\Users\username\AppData\Local\Temp\AnsysWBDumpfile.dmp". This strange since up until today this worked perfectly. Furthermore, if I want to edit a model in Mechanical, it doesn't start correctly and I only get a grey screen. I already tried various solutions I found on other pages, but nothing seems to work. I also reinstalled all Ansys products. Can you help me to fix this?
