The reason is that your ORCA output file is in Unicode encoding, however Multiwfn can only parse text file in ASCII encoding. You can use some softwares such as Ultraedit to convert the file to ASCII (File - conversions - Unicode to ASCII).
If your file was generated under Powershell environment, it is worth to note that the text file produced via redirection is in Unicode by default, you can configure Powershell to make ASCII as the default encoding (the steps can be easily found via Google). Alternatively, you can use "cmd" terminal instead, the redirected text file is always in ASCII.

It is best to compress the output file and send it to me. Based on your keywords, I cannot easily figure out the reason why Multiwfn fails to plot spectrum for your file.

Please update to the latest version of Multiwfn and retry. If latest version also doesn't work, probably the keywords you used are incompatible with the spectrum plotting module of Multiwfn, please upload your ORCA output file or send it privately to my E-mail (sobereva[at]sina.com), I will check the reason.
