Additional Context
I installed each version back to 10.34.0 and that was the newest one that worked. Seems like one of the main changes is adding the Vite plugin in 10.35.0, maybe related?

Hi @garand, thanks for writing in.
It looks like the vite plugin is making it into your application code. Ideally your build system should be able to figure out that this dependency is only used in configuration files that themselves aren't making it into the build.
We've had a similar issue before in #18215, there's not much we can do here beyond advising you to have a look at your build system and figure out why the plugin ends up in your application code.
Let me know if something's unclear.
