Draftsight crashes on open or save. Changing process affinity temporarily stops crash.

On my machine when I try to open or save a file in DraftSight the program crashes. After lots of troubleshooting i found that changing the processor affinity for DraftSight.exe to a single 'core' prevents this error.

Steps to reproduce:

  1. Open draftsight
  2. Open File menu > Open
  3. Crash (The program must close .....)

 

  • DraftSight 2017 x64 SP2
  • Windows 10 Pro 1703
  • AMD Ryzen 1700

Troubleshooting steps tried:

  1. Reinstall DraftSight
  2. Re-activate DraftSight
  3. Also happens in Safe mode.
  4. Disabling SMT
