I upgraded from Teamcity 9.1.1 to teamcity 9.1.3 yesterday.
Since then we have had our nunit build step start to fail with this error:
Anyone else seen something like this or know where I should be looking to fix this? I have attached some images to show our build step and the output in the build log.
Just to add to this, I have uninstalled the 9.1.3 agent from the build servers that I had installed it to. I have reinstalled the 9.1.1 agent, and everything is working fine again. All Nunit tests run properly with the 9.1.1 agent installed.
