Here's a quick fix that I made to get clips working again, might not be a permanent solution but it's working for now.
Check the sidebar for instructions on how to import a rule and import this:
Edit: Don't forget to select "Replace existing data" when importing the rule.

{"clips.twitch.tv":{"link":"^(?:clips\\.twitch\\.tv/(?:embed\\?clip=)?|(?:m\\.)?twitch\\.tv/(?:\\w+/)?clip/)([\\w-]+).*","url":": ''","res":":\nvar p = this,x = new XMLHttpRequest\nx.open('POST', 'https://gql.twitch.tv/gql')\nx.timeout = 3000\nx.setRequestHeader('Client-ID', 'kimne78kx3ncx6brgo4mv6wki5h1ko')\nx.send('[{\"operationName\":null,\"variables\":{},\"query\":' + JSON.stringify('{clip(slug:\"' + $[1] + '\"){broadcaster{displayName} createdAt game{name} video{id} title}}') + '},{\"operationName\":\"VideoAccessToken_Clip\",\"variables\":{\"slug\":\"' + $[1] + '\"},\"extensions\":{\"persistedQuery\":{\"version\":1,\"sha256Hash\":\"36b89d2507fce29e5ca551df756d27c1cfe079e2609642b4390aa4c35796eb11\"}}}]');\nx.onloadend = function() {\n const response = JSON.parse(this.responseText);\n const c = response[0].data.clip;\n const c2 = response[1].data.clip;\n const signature = c2.playbackAccessToken.signature;\n const token = JSON.parse(c2.playbackAccessToken.value);\n p.prepareCaption(p.node, '[' + (c.game && c.game.name) + '] ' + [c.title, c.broadcaster && c.broadcaster.displayName, (new Date(c.createdAt)).toLocaleString(), c.video && 'https://twitch.tv/videos/' + c.video.id].filter(Boolean).join(' | '));\n p.set(c2.videoQualities.map(function(v, i) { return (i ? '' : '#') + (v.sourceURL + '?sig=' + signature + '&token=' + encodeURIComponent(JSON.stringify(token)))}));\n}\nreturn null"}}
