Unsure if this is a bug or some behaviour that I’m not aware of.
Restarting sublime (4102) appeared to disable some plugins (LSP-pyright in this case).
Inspecting the console:
Package Control: Upgraded LSP-pyright to 1.1.62
Package Control: Upgraded SublimeLinter to 4.16.3
ignored packages updated to: ["LSP-pyright", "Markdown"]
I had to manually enable these packages through package control, even after another restart.
