v.124.0.6367.60-1 does not launch

I tried launching Chrome this morning after updating to the latest version, but only had a blank, non-rendering window appear. It was like Chrome was in the early stages of showing the browser window, then got stuck. CPU usage was higher than normal (6% on my laptop, which is about one full CPU thread).

I'm running on NixOS Unstable (24.05), Gnome 45.5, Flatpak 1.14.5.

Current workaround is to downgrade to [123.0.6312.122-1](https://github.com/flathub/com.google.Chrome/commit/10261d0be19bfc537635eed8266ae1bc4dae96ac).
