I’m running into all sorts of issues getting dev containers to work in VSCode after upgrading (search only works on open files, VSCode thinks open files are dirty and frequently prompts user for additional actions on save, etc.).
One of the issues with volumes, however, seem to be due to case sensitivity. If your volume path did/does not respect case, that might be the source of some of the errors here. Pre 2.2 update, case sensitivity didn’t seem to matter, now it does.
