Experiencing this issue on my realm as well. Realm is little over a year old on bedrock. First experienced the lag spikes in the overworld while traveling by minecart on my way to a nether portal. After I got back from the nether I experienced my first crash only after I returned to the scene of the lag spikes. Crashes occur anytime I return to that area now. I’ve tried loading previous saves, but they all seem to have the same issue in the same area.
