Please also see the suggestion how Codex thinks it would fix it:

#451 (comment)

[oleg-shilo]

@UweKeim , the fix is ready.
If you are waiting for it, I will release it right away. If not, then I would want to add #453 before I made another release.

Thanks, @oleg-shilo, I've pinned our CI-CD builds to version 4.13.1, so it is not that urgent.

[oleg-shilo]

Excellent, thank you.

[oleg-shilo]

Done, you can try v4.14.3.0
This should be OK unless a very exotic .NET SDK distro is used.
Please let me know how it went.
