A crash of plugin host may be caused by any plugin and is not necessarrily related to Package Control.

I'm running into this same issue, and it does appear to be connected to Package Control. If I install a fresh version of Sublime Text 4 (Build 4126) and then "Install Package Control", I immediately get this error.

I am on an M1 Mac, OS version 12.0.1

Here is the contents of my console:

reloading python 3.3 plugin Package Control.1_reloader
reloading python 3.3 plugin Package Control.2_bootstrap
error: plugin_host-3.3 has exited unexpectedly, some plugin functionality won't be available until Sublime Text has been restarted

I have the same issue, also on a fresh download of ST 4126. I rm -rf ~/Library/Application\ Support/Sublime\ Text, and everything works fine, then I Cmd+Shift+P -> Install Package Control, which gives me two popups: first, "Package Control was successfully installed", then "plugin_host-3.3 has exited unexpectedly".

Running MacOS Monterey (12.1) on a M1 Mac. Entire console contents from start to installation and plugin_host trouble:

I also had the same issue as above running on an M1 computer with both OSX 12.0 and 12.1.

I think I was able to resolve it by running Sublime Text via rosetta just like I had to do with my iTerm for brew and python 2 to work properly. The steps to do that are:

• go to the application folder
• made a copy of "Sublime Text" renaming it something like "Sublime Text Rosetta"
• right click on the copy & "Get Info", check "Open in Rosetta".

I will update here if I find any issues with this approach down the line.

I think the root cause is probably python 3.3 (some library dependency) being incompatible with OSX 12 on Apple Silicon. Since ST4 does ship with its own fork of python 3.3, that fork might need updating for OSX 12.

My hunch is it being caused by oscrypto library, which utilizes openssl library for HTTPs connections on MacOS. If openssl API is different on M1 it may cause plugin host to crash.

You could try to disable oscrypto downloader via Package Control.sublime-settings

    "downloader_precedence": {
        "windows": ["wininet", "urllib"],
        "osx": ["urllib"],
        "linux": ["urllib"],
    },

or try out latest Package Control 4.0.0 beta releases https://github.com/wbond/package_control/releases, which optionally uses a more up-to-date oscrypto library and falls back to urllib automatically.
