Error connecting to ExchangeOnline with PowerShell 7 - "Error Acquiring Token:...."

wow that worked, thank you.
i had something similar. i put here the details, to help others with same problems finding this solution.

ExO tried to open a link instead of a login screen

https://localhost:58964/?code=.....

with ERR_CONNECTION_REFUSED. then nothing happens.
i had to CTRL+C to kill the prossess. than this error appears:

PS > Connect-ExchangeOnline -UserPrincipalName email address removed for privacy reasons

doing your solution i get:

PS > Import-module ExchangeOnlineManagement -usewindowspowershell

WARNING: Module ExchangeOnlineManagement is loaded in Windows PowerShell using WinPSCompatSession remoting session; please note that all input and output of commands from this module will be deserialized objects. If you want to load this module into PowerShell please use 'Import-Module -SkipEditionCheck' syntax.

and than it works.

this fix was for ExO v2, cause it didnt support PS7. looks like there is some incompatibility issues again, now between ExO v3 and PS7. here are my versions:
