Have you tried ~/.chromium-browser.init?

See https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1837746 and https://askubuntu.com/questions/1214392/chromium-snap-conversion-command-line-options

I could also be that the snap version of Chromium, or the libraries included with the snap, are not built to support the GTK 4 version.

This is what worked for me: creating and adding CHROMIUM_FLAGS="--someflag" to ~/.chromium-browser.init
