I have this recurring issue of MySQL Workbench (v6.3.7) query crashing on execution. The OS is Windows 10 Home, and the application event log shows the following message pointing to faulting module as C:\WINDOWS\SYSTEM32\ntdll.dll:

Same issue. Found a reference in MySQL bugs recommending reverting to 6.3.6 511, which seems to have resolved the issue for me.
