Something blocking HA wrapping up start-up phase

The problem

HA log complains that it couldn't complete start-up phase, and asked me to send the diagnostic data to you folks (below).

This looks to be related to the HACS Mitsubishi integration, which is also flagged as using deprecated constructs, so (shrug). It might also be due to switching to a TP-Link ER605 router, which is more biz-oriented and is doing some funny DNS stuff.

Also: Settings -> Repairs -> "..." -> System information isn't working? Shows Core and Supervisor metrics, but has an endless spinner above those. DNS stuff again?

What version of Home Assistant Core has the issue?

core-2024.5.5 ? Sys Info not displaying; last backup is 5.4 .

What was the last working version of Home Assistant Core?
