Hi there, I have been through a lot of these threads and haven’t found a solution.
I had a working install a while back and installed a few plugins (material theme, elixir ls, copilot), and all was good for a minute. I tried coming back to it after a couple of months of not using it and it started crashing.
After a long time trying to debug, I decided to start from scratch and see if I could make it work. I deleted the app and its settings, freshly installed the newest version (4169) and installed package control.
Immediately after installing package control, I started getting the same message as before.
plugin_host-3.3 has exited unexpectedly, some plugin functionality won’t be available until Sublime Text has been restarted
Can’t for the life of me figure out what is wrong 
For reference, I am on an Apple M1 Pro (if that changes anything)
Here is the dump from the sublime console:
