I haven’t used Workbench for over a month, when I came back to it I can no longer compile locally
i assume that means it was working at one point? if so, are you working with a project that you know once compiled fine?
have you updated VSCode recently? if not, give it a try:
looking at your screenshot above, i can tell Workbench is installed and running because you have our action buttons top-right as well as project settings displayed in the status bar.
try running Particle: Audit Environment as described here and share the non-sensitive bits in this thread.
beyond that, the only thing that caught my eye is the path /c:/B/Particle_Programs/tester/workplease - that seems wrong. is that project located on some sort of remote drive (e.g. dropbox, etc) or otherwise non-standard directory? if so, try creating a project in a standard directory.
the errors you are reporting are a bit odd in that you show “cannot find task” but then show the output from running that task so
