PnP Search owstaxidmetadataalltagsinfo link not responding

Hello everyone,

Hope you are all doing great. I have a question regarding PnP search (version 3.6.3.0.). We have the page setup up for a long time and suddenly, at one point, the links stopped working. I have very low experience with PnP, so I am not sure what is going on. Picture attached. I see when I click on the link that the part #owstaxidmetadataalltagsinfo:'keyword' is added (keyword part depending on the link of course), but nothing is happening with the result page (it doesn't refresh or load desired data). Any kind of advice is appreciated.

Thank you for your time.

Kind regards
