Inkscape has a policy file /etc/ImageMagick-7/policy.xml (or some other 
number). It has lines like:

# grep PS /etc/ImageMagick-7/policy.xml
  <policy domain="coder" rights="none" pattern="PS" />
...

which tells it to not allow ps, etc., files.

If you create a file like:
$ cat ~/.config/ImageMagick/policy.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE policymap [
  <!ELEMENT policymap (policy)+>
  <!ATTLIST policymap xmlns CDATA #FIXED ''>
  <!ELEMENT policy EMPTY>
  <!ATTLIST policy xmlns CDATA #FIXED '' domain NMTOKEN #REQUIRED
    name NMTOKEN #IMPLIED pattern CDATA #IMPLIED rights NMTOKEN #IMPLIED
    stealth NMTOKEN #IMPLIED value CDATA #IMPLIED>
]>

<policymap>
  <policy domain="coder" rights="read|write" pattern="PS" />
  <policy domain="coder" rights="read|write" pattern="PS2" />
  <policy domain="coder" rights="read|write" pattern="PS3" />
  <policy domain="coder" rights="read|write" pattern="EPS" />
  <policy domain="coder" rights="read|write" pattern="PDF" />
  <policy domain="coder" rights="read|write" pattern="XPS" />
</policymap>

imagemagick will work on postscript files again.

 Make sure you have Ghostscript version 9.24 or later:
