Oh yeah that appears to be same issue.
Thanks for the report, should be fixed in the latest beta.
I am on the Steam Client Beta and can confirm the Browse Local Files option is working for me today
Ah yes, I forgot to retest this, can confirm it works now.
Nothing extracted yet.

Please describe your issue in as much detail as possible:
