I got this error when trying the HostBase demo

I tried it in Ubuntu 20.04, and the log was attached here.

I'm getting this, too. (At least I think this is the error that @zhangzq71 is asking about; there are several in the log.)

Specifically:

Unhandled exception rendering component: Could not find 'StardustDL_RazorComponents_Markdown.highlight' ('StardustDL_RazorComponents_Markdown' was undefined).
      Error: Could not find 'StardustDL_RazorComponents_Markdown.highlight' ('StardustDL_RazorComponents_Markdown' was undefined).
