Symptoms

The scene editor for quests displays a blank window instead of the expected information.

There is a DLL file called flowchartx64.dll which is involved in the operation of the scene editing window. This is apparently some sort of ActiveX/COM component that ships with the Creation Kit on Skyrim, Fallout 4, and Starfield. I don't know if the files are functionally different with each game, but I know for sure the one for Skyrim SE does not work.

When the Creation Kit is first installed it asks if I want to register this DLL file. I say yes to the prompt. It either is not being registered properly in the Proton instance or the DLL itself is somehow not being processed properly.

Reproduction

Skyrim Special Edition first needs to be installed by Steam.
Then you can install the Skyrim Special Edition: Creation Kit afterward.
Once it is installed, start the Creation Kit.
You should get a prompt about the Scripts.zip file, which can be safely ignored.
You should also have another prompt to register the flowchartx64.dll file. Say yes to this prompt.

When the CK finishes loading, hit the "Open File" button. Select Skyrim.esm from the file menu. Double click on it, then hit OK to start it.
It will take some time to load its information.

When done, open the "Caravans" entry from the list of quests.
Click the Scenes tab.
Select the one listed in the menu.
At this point you should see that the scene window is empty.

What you should see instead is something like this:
