Coverage session finished with errors: Unknown standart IL prefix

In order to generate weekly coverage results, we start the dotCover console runner process with a predefined config xml, but we get following errors:

[JetBrains dotCover] Coverage session finished with errors: Unknown standart IL prefix
[location] = C:\Build Agent\work\2e477e1decf4e7a0\Profiler\Kernel\Windows\Native\Solution\core\src\IL\ILCommands.cpp(90)
[function] = const struct ILCommand *__cdecl FindILCommand(const unsigned char *); Unknown standart IL prefix
[location] = C:\Build Agent\work\2e477e1decf4e7a0\Profiler\Kernel\Windows\Native\Solution\core\src\IL\ILCommands.cpp(90)
[function] = const struct ILCommand *__cdecl FindILCommand(const unsigned char *); Unknown standart IL prefix

The process fails with exit code -2. We use the 2018.1.2 version.

Unfortunately i didn't find a solution for this problem online. 

Thanks in advance.
