Last week SFDX stop working to me. In all the instances I have, SFDX force me to reconnect the instance. When I try to reconnect I receive this error: Cannot read property 'getInstance' of undefined
I tryed to update sfdx with de SFDX update command and uninstalling and installing again the Salesforce CLI.
I remove all extensions and installing again (Salesforce extension pack) and to finish I uninstall the Visual Code too. Always the same error.
can anybody help me, please?
