Build failed in Win10 + WSL2

Discussed in #3475

Hello, I have a failed build in WSL2 (Win10Pro).
The changes which cause the error were introduces several weeks ago, but I don't see any issue reported. So, maybe I'm doing something wrong.
What I've done:
fprime-bootstrap clone https://github.com/AlesKus/fprime.git (for now, my fork is synchronized with devel branch 637e812)
cd fprime
. fprime-venv/bin/activate
./ci/tests/Framework.bash
The output:

[INFO] FP Util in /home/alexkus/fprime/fprime running generate
[INFO] FP Util in /home/alexkus/fprime/fprime running generate --ut
[INFO] FP Util in /home/alexkus/fprime/fprime running build with 28 jobs

It looks somewhat similar to #3030. But, again, I don't see any issues or discussions about this, therefore my questions are:

1. Does anyone observe this behavior?
2. Is my command line sequence correct?
