It is 100% reproducible for me. Disabling File Watcher in the Prisma Extension settings makes the problem go away. Is disabling that setting safe to use as a work-around for now?

The fix is now in the latest 4.4.0 version on the marketplace https://marketplace.visualstudio.com/items?itemName=Prisma.prisma 🎊

For those who disabled the File Watcher functionality, you can enable it again.
