Novice question about Arduino toolchain

Hi @Bert75 ,
Welcome to Embeetle!

Thank you for reaching out to us. I looked into your problem, but can’t pinpoint right now the cause (and can’t reproduce it either). I’d need a bit more information. Are you working on Linux or Windows? Could you please record the steps leading to this error? Perhaps you can use this free tool for recording:

We can also plan a remote session. We can use Teamviewer or Chrome Remote Desktop. When would suit you best?

Kind regards,
