Feedback for "Enable Process Isolation": this has sometimes strange effects and errors on PWAs (Progressive Web Apps), especially when working with different browser profiles. The PWAs are sometimes not loaded till the main Edge Browser process (with main or second profile) is triggered/opened, pwahelper.exe get's sometimes stucked and closes. Without this setting PWAs with different profiles work perfect without a problem. I hope this feature is still in evaluation from Microsoft as it is not enabled by default, for now i can't recommend this setting and leave it to not configured.
