Error Code: Out of Memory | WordPress Backend Pages

Ok, I tested it on Firefox and Edge.
It managed to load on Firefox but it took almost a whole minute to load.
With Edge, I had the same result as Chrome, “Error code: Out of Memory.”

So now I’m not quite sure what to think.

Alright, here is our website: https://www.blickindustries.com/

Yeah, our site is somewhat on the slow side for sure, but never to the point where it times out.

The front-end site is performing as usual but on the back end, the Pages menu is definitely lagging.

If you would like to recreate the error, I can provide a staging site that is behaving in the same manner.
