Issue when importing calendars from a URL, getting a long list of UNKNOWN TYPE and then some events show in the backend, but only if I turn off "Hide past events" (an example of this can be seen in the attached images. the event which is in 2018 doesn't show with "Hide past events" set to "yes"

. Additionally, none of the calendar events are showing in the frontend. This appeared only in this 3.4.42 update, it was working fine in 3.4.40/41 (excepting the frontend issue in 3.4.41). The events that are showing are unclear, it's not specific to repeating/non-repeating. I have attached one of the ICS files that we link to which causes this issue and isn't private (although none of them import). It's an export of a GCal.
