"Android Not Responding" background freeze

I disabled all my other profiles and left only the problematic profile enabled (in arcanechat I have control over start_io per profile) and collected the following log, in the log from the start it was all slow and getting "Android Not Responding" due to some background thread while I could use the app despite some operations like long-pressing a message and reacting being very slow due to getChatMsgs()

the ANR dialog would keep appearing over and over so some background thread got permanently blocked calling some core operation/api, I was trying to react to a message and remove reaction while the app was kinda frozen and very unresponsive with the ANR poping up until eventually it did my actions

core-only log:

Start by tracing the background activity shown in src/scheduler.rs, src/imap.rs, and src/net/dns.rs, then compare it with the reported getChatMsgs() slowdown and repeated Android Not Responding dialogs. Use the core-only log and the single problematic profile to reproduce the freeze. Done means identifying and fixing the blocking core operation so foreground actions remain responsive.
