Issue Description

Hello, we're trying to run u3d to execute our build command. Editor.log is not printed to the terminal.

Here's what is printed:

Looking through the code, we thought this was an issue with race condition, and we added sleep(3) at line 118 of unity_runner. Here's the log that was printed afterwards:

u3d was installed in a Windows Server 2019 with Ruby installed using Ruby Installer+msys2. The OS is running in a VM (with graphics) within an Ubuntu host. Although the logs were from GitLab, we also tried running u3d manually on cmd only to get the same result. We also checked to make sure that editor.log existed in the correct file path and was getting updated (by Unity) normally.

I am having a similar issue where u3d is not printing the logs into the output in a Jenkins setup. Running on Windows 10. I used the ruby installer.

Command line looks like this:
u3d run -- -quit -accept-apiupdate -batchmode -logFile Builds\\Logs\\GameName.log -projectPath \"GamePath\" -buildTarget Win64 -executeMethod BuildClass.BuildMethod
