Command line export doesn't exit if there is a build error

[miv391]

Tested versions

Reproducible in v4.3.dev6.mono.official [89850d5]

System information

Godot v4.3.dev6.mono - Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 6GB (NVIDIA; 31.0.15.5212) - Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz (4 Threads)

Issue description

If I try to export the project from command line but there is build error, either GDScript error or C# error, Godot executable doesn't exit. I need to press Ctrl-C to exit.

A build error seems to cause this problem every time. But I also noticed that sometimes even working build doesn't exit cleanly if I ran the export command from Window's bat-file. However, I don't know to reprocude that.

I also wonder, if it would be better to instantly quit the exporting process, if the build fails. Now the process continues with the savepack.

This is a somewhat shortened and anonymized output:
