Cannot reproduce here.

Does this also happen when you load File > Factory Settings?
Could you share your bledfile (so we are all on the same page)?
Does this also happen with the newset build from https://builder.blender.org/download?

Marking as incomplete until we have these tried...

Still cannot reproduce.
Is this still an issue with the latest buildbot build?

I could reproduce with latest( c94f806dc7 ) on Win10. But can not reproduce on Linux.

It also happens in the following way.

Create shape key
Set the value of shape key to 1
Enter sculpt mode
Hit tab many times

I was able to confirm this on windows 10 x64 2018-11-28 hash 4c6e7ef11f

I've narrowed it down somewhat. The crash is triggered by the transition from edit mode to sculpt mode if one of the following is true:

The object has only a base key, OR
The object has a base key and any shape key with a nonzerovalue.

Other things:

It doesn't matter if the edit -> sculpt transition is done by changing tabs, using the drop-down menu, or the radial menu: all will cause Blender to crash.
It is triggered only by directly changing from edit mode to sculpt mode. Going sculpt->edit->another mode ->sculpt works fine.
You can change the value of the key from within sculpt mode and sculpt as normal whatever the value of the key without crashing.
If you sculpt on a key that is at 0.0, any changes will be immediately discarded. However, changing the key value to 0.001 or higher and the changes will stick.

Related to this is #58075, which crashes under the same conditions (only one shape key, or one or more nonzero shape keys) when switching from edit mode to vertex paint mode.

Just a shot in the dark:
Does this also happen when blender is called from the commandline with the --threads 1 option?

Could reproduce here with only one basis shape key.

I can reproduce the bug on 27cccaeccd with --threads 1 option.

But It can not reproduce with --debug option. Then terminal displays following errors in edit mode.

Pass : Edit Mesh Face Overlay Pass, Uniform 'viewportSize' not found!
Pass : Edit Mesh Face Overlay Pass, Uniform 'edgeScale' not found!
Pass : Edit Mesh Face Overlay Pass, Uniform 'dataBuffer' not found!
