Momentary error shown when trying to build strategy with external reference

I have been able to replicate an error I have been seeing letely on one of the strategies I developed, so I can leave here for spotware to address and let me know how I can fix this.

If I add a reference to an external library (Accord Math in this case), when I click on build, I see an error showing for a second saying:

"The process cannot access the file [path to the compiled robot].algo because it is being used by another process".

After that it shows "Build succeeded".

To replicate this, create a new, empty robot, and add a reference to the Accord.Math library. You can find it here, I added it via wetransfer to make it easier to replicate. No need to add any code, just add the reference and hit build.

You will withness the same behaviour.

The library can be downloaded here: https://we.tl/t-SijNzIPTbb

Or through the official site for the Accord framework.

Why is this showing up, and how can it be fixed?

Thank you.
