Unreal crashes when using HammEUr plugin

I bought the plugin to import Valve maps to Unreal, but it always crashes Unreal 4.27 when I try to import Props (models). It is HammUEr 2.2 for 4.27. Anyone experienced this issue, or anyone successfully got props imported with this specific version?


Having the same problem, would greatly appreciate it if someone knows a fix for this
