I have a large repository with JS files which I allow to be imported in TS files with `allowJs: true`. I’ve noticed that whenever that option is active, I can get errors in TS language server and when running `vue-tsc`. Unfortunately, I can’t provide full repository since it’s internal project, but it can consistently be reproduced by toggling that option. **`vue-tsc` error** ```sh npx vue-tsc npm notice run npx npm notice run 'vue-tsc' ▎ TNB ACTIVE — `typescript` is the tsgo-backed fork panic: runtime error: invalid memory address or nil pointer dereference [recovered, repanicked] [signal SIGSEGV: segmentation
