I've been working using VSCode to develop Lightning Web Components for over 6 months, however today after restarting my machine I am unable to authorize my org. It was able to redirect me to the login page, and after I successfully log in to my org an error is thrown.
13:35:57.363 sfdx force:auth:web:login --setalias SME --instanceurl https://test.salesforce.com --setdefaultusername
ERROR running force:auth:web:login: Parse error in file C:\Users\NSDO\.sfdx\alias.json on line 1 13:37:10.766 sfdx force:auth:web:login --setalias SME --instanceurl https://test.salesforce.com --setdefaultusername ended with exit code 1
Before all that on the 30th of March I noticed that VSCode was updated to the Feb 2020 version and I suspect that this could have something to do with it. However, I have tried updating sfdx to 7.53 (previously from 7.52) and even uninstalled and re-installed VSCode (back to Oct 2019 version which I have been using) but this error is still there. Also that .sfdx\alias.json file is nowhere to be found.
Any help will be greatly appreciated.
