Crawler keeps causing crashes

We have the LSCache WP plugin installed on 2 sites one with & one without QUIC.cloud. I never tried to enable the crawler on the one that’s cached separately since I didn’t see the need but even after restarting the server then we keep getting fatal errors (E_ERROR) when trying to manually run the crawler for preloading the cache for the QUIC.cloud cached site. Here’s the most recent one:
