I believe this fixes #52698, although I don't have a dump for that issue so I'm having to deduce what I think happened based on the stack alone. Unfortunately the stack also has some frames inlined so there's a bit more guessing than usual: The stack shows that we ended up in Comparer.Compare and it threw; the only exception that it throws directly if the thing being compared isn't IComparable. There aren't many uses of ImmutableSortedDictionary in Roslyn, but the one specific one that makes sense to be under GetDocumentState is the one we have inside our TextDocumentStates type. And that one is one where we normally pass in a custom comparer to pass in DocumentIds, so it seems logical that we somehow ended up with a map that didn't have our comparer. It turns out the Empty member we had didn't specify one, so if we started with the Empty member and then added stuff from there, we'd end up with such a map without a comparer. Why didn't we see this right away? Because it turns out we only have a few uses of .Empty, most of which are with source generated files. And even then we often are creating the source generated collections with something else.

If we are processing edits through TryApplyChanges for closed files, we'll make a series of changes in rapid succession: we'll have one change that may open the file in an invisible editor, then we'll edit the file, and then close again. The Solution object would then be holding onto the old Compilation with several changes queued, which would root the intermediate states that still pointed the editor contents and their change lists which can be large. Once a Compilation was requested for this new file, we'd process all the changes and free the memory, but if the file is closed we might not get to that right away.

Troubleshooting conflicts
Identify authors of changes which introduced merge conflicts
Scroll to the bottom, then for each file containing conflicts copy its path into the following searches:
Usually the most recent change to a file between the two branches is considered to have introduced the conflicts, but sometimes it will be necessary to look for the conflicting lines and check the blame in each branch. Generally the author whose change introduced the conflicts should pull down this PR, fix the conflicts locally, then push up a commit resolving the conflicts.
Resolve merge conflicts using your local repo
Sometimes merge conflicts may be present on GitHub but merging locally will work without conflicts. This is due to differences between the merge algorithm used in local git versus the one used by GitHub.
