electrum yields the following error on startup:

	> electrum 
	Error: No module named 'qrcode'. Try 'sudo pip install <module-name>'

python-qrcode is correctly specified as input in the package's
declaration:

There was an issue with the upgrade of the python-qrcode package from
version 5.3 to 6.0 [1], which meant that the output didn't actually
contain any code [2], hence the error you are seeing.

I've just pushed a fix to the package [3], so if you update Guix (by
running guix pull, or otherwise) and then upgrade electrum, that should
resolve the issue.
