Well, TD-er here…
I did also have issues when using the latest dev (upto 4 or 5 days ago at least, the last time I tried)
My laptop is unable to complete a build then and my desktop only fails every now and then.
The errors seem to suggest some files are being deleted while a build is in progress, just like VS code is checking some other PIO envs in the background.
A lot of my users reported similar issues, also tested with the dev version and some also never could get a build to complete.
This issue ticket by @deladriere is reporting the build problem. If I open another issue it seems to me that it will be a duplicate of this one. I don’t want to spam the issue tracker with another topic about it.
