thonny: "ssl certificate expired" trying to install Micropython firmware

I was following along with this video and tried to update my firmware using Thonny. When I clicked Install, my IDE attempts to download micropython but it fails with a “certificate expired” error.

To get around it for now, I just installed Micropython manually from the Raspberry Pi Pico Getting Started page. After launching Thonny, I was automatically connected and could run commands in the REPL and run programs using “Run current Script”, F5.

Is the SSL cert something I can fix on my end?
