Lightroom CC 9.3 crashes immediately on start.  Photoshop works fine.  Was working last week after installing old directml.dll file.  Stopped working today.  Followed all available advice, then uninstalled and reinstalled, still crashes on start.  Instead of directml.dll error from last week, now it is EXCEPTION_ACCESS_VIOLATION" exceptionCode="0xc0000005.

Hi Richard,

Have you installed Windows Insider Preview by any chance? We have got quite a few crashes reported for directml.dll which are originating from Insider Preview Builds.

This has also been documented in a blog post:
Starting with the last build, some games and applications may crash at launch or fail to install. We’ve identified the root cause and are working on a fix for a future flight.
If you are on an Insider Preview Build, you can disable GPU from Device Manager and that should prevent the crash until the issue is fixed in the Preview builds.
