Error when trying to execute powershell script via "Command line runner"

Hi! I am unable to execute a powershell script using the "command line runner".

The command I am trying to run is: 'powershell -command ./myfile.ps1' (I wrapped the command in a bat-file, but I got the same error, the stack trace below originates from when I tried with the bat-file). Like I said, this command runs fine on the server
The command works fine if I run it directly on the server. What happens is that the build process never finishes and I have to manually stop it. Having looked through the log files, I found the following stacktrace in "teamcity-agent.log" found in my buildagent-logs directory:

I also found a system error occurring at the same time using the eventvwr:
"Generate Activation Context failed for C:\TeamCity\buildAgent\plugins\stacktracesPlugin\bin\x86\JetBrains.TeamCity.Injector.exe. Reference error message: The manifest file contains one or more syntax errors."

Finally, if i view the thread dump when I am attemting to run the build configuration, I get the following stack trace:

Failed to get command line of the process.
