How to reproduce:
1. Open the attached "FindKernel.zip"
2. Navigate to File > Build Settings (Ctrl + Shift + B)
3. Check the "Server Build" option
4. Click Build And Run
5. Select the "Server Build" in the "FindKernel" Project folder

Expected result: FindKernel works and there are no errors or continuous code spam
Actual result: FindKernel is not found and the server gets flooded with "NullReferenceException" lines

Reproducible with: 2020.2.2f1, 2020.3.17f1, 2021.1.19f1
Not reproducible with: 2019.4.30f1, 2020.1.17f1, 2020.2.1f1
Could not test with: 2021.2.0b9, 2022.1.0a6 (No "Server Build" option)

Note: When the server build starts the "NullReferenceException" spam floods the errors and "ArgumentException" in the beginning. To avoid that click once on the server code
