The bundle generator fails after adding a dev dependency

[MarkStega]

Bug report

The bundle generator fails with Error: Something went wrong - getSymbolsUsingSymbol returned null but expected to be a set of symbols (symbol="D:/Miscellaneous/d-b-g-issue/node_modules/@babel/types/lib/index")

I have a complete reproduction in a repository at https://github.com/Material-Blazor/d-b-g-issue. The project is a tiny React library with two toy components. The goal is to create a rollup and an accompanying .d.ts file.

If you clone that repository do the following to reproduce:

1. Change directory to the cloned root
2. npm i
3. npm run build

This will compile, rollup, and generate the .d.ts file with no issue (output is in the .rollup directory)

Now, checkout the branch 'DemonstrateIssue' and do the following:

1. delete the .rollup directory
2. npm update
3. npm run build

And observe that the bundle generator fails with the opening message. The only change is the addition of two dev dependencies in package.json.

Can you try this approach #347 (comment) if see if it helps?

"types": [] added to my tsconfig & I no longer have the error. You may want to add a note to that effect in the readme since at least two of use have tripped on this...

Thanks for the very prompt response!
