I am having presumably the same issue. I was prompted to update to using the Ivy-based language service, I did, and VS Code is now informing me that it's crashing so much that it won't restart anymore. The console shows this error:

var sourceFile = program.getSourceFile(fileName);
                                     ^

TypeError: Cannot read property 'getSourceFile' of undefined

    at processTimers (internal/timers.js:492:7)

I also have a ton of errors saying "No config file for <whatever .html template file I have open at the time>". Note that this is the same repo, it's not across multiple repos. All of the lines related to enabling the Ivy language service are pointing to the same tsconfig.json file.
