I'm having the same problem. For me, I'm not getting redirected to my salesforce Org. This is what I see in VSCode
12:22:15.474 sfdx force:auth:web:login –setalias DevOrg –instanceurl https://login.salesforce.com –setdefaultusername » Warning: force:auth:web:login is not a sfdx command. Did you mean auth:web:login? [y/n]: » Error: Run sfdx help force for a list of available commands. 12:22:21.923 sfdx force:auth:web:login –setalias DevOrg –instanceurl https://login.salesforce.com –setdefaultusername ended with exit code 127

There is a current regression bug in the Salesforce CLI latest version causing the issue.
For now, you can work around by running below in your vscode terminal
Notice that now you need to use
sfdx auth:web:login
instead ofsfdx force:auth:web:login
for authorization.
