This issue was resolved many times by disabling the Fault Tolerant Heap of Windows.
You can check by looking for this registry entry:
Go to the
HKEY_LOCAL_MACHINE
and
HKEY_CURRENT_USER
versions of
Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers\matlab.exe
和删除
FaultTolerantHeap
entry.
To fully disable this service in Windows (or to understand what this service does), please read the documentation:
If your issue is not resolved after disabling this service, then please create a Technical Support ticket.

Another possible way to solve this issue is to regenerate your preferences.
If you still need assistance after doing this, please create a service request.
