The “The PlatformIO task detection didn’t contribute a task…” issue has recently popped up again, though it only affects a few people and couldn’t be reproduced by Ivan.
The issue is just an annoyance. It doesn’t break anything. When it originally appeared a year ago, deleting .vscode/tasks.json solved the problem for the affected project.
I’m more concerned about the “gdb/regcache.c:697: internal-error”. Can you provide more context? What action did you perform when it happened? What’s the log before and after the error?
