VS Pro Map node makes it crash after build

VS Pro with MM2 works unless I am using VS Pro Maps.

(Although VS Pro with VS Pro Obj node works and builds ok)

Steps to reproduce:

1. Clean project with a simple graph

2. Add constant node and connect it to VS Pro maps (doesn't matter)

3. Generate

4. Watch it is working OK in Editor

5. After build it's crashes on attempt to run.

Only lines in console (development build):

> LinuxPlayer(192.168.0.190) The file '/home/user/Code/unity/Projects/newmapmagictest/BuildLinux/Run_Data/level0' is corrupted! Remove it and launch unity again!

[Position out of bounds!]
(Filename: ./Runtime/Serialize/SerializationCaching/CachedReader.cpp Line: 220)

Removing "level0" and restarting a build file doesn't help. It prints "development build" but nothing happens then.

IL2CPP/Mono build switch doesn't matter, 2019.4.19 LTS, Linux/OpenGL, Net 4.0

Please note that VS Pro Obj node is working correctly. Also VS Pro runtime spawn works too.
So VS Pro works. It only happens when adding a VS Pro map node and trying to build.
