Can't update a repeating event on a synced google calendar locally

[Yodamien518]

On my events, I have automatically created meets, but the link to the meet is in the description and is not joinable from minimal event view.
So I wanted to set the link to the meet on the url field, but when saving the modification, a popup asking if I want to update locally the event as it is a synced event appears, and when accepting the modification as a local update, nothing happens, the modification popup is still open and closing it will cancel the modifications and saving again triggers the same behaviour.

I have seen a different popup for a repeating event asking if the modification should be applied to all events or not, but I don't have it for this one I am having an issue with.
Any idea on why that is the case, or how I could see any error ?

@Yodamien518 When you click the calendar status button in the status bar, the popup shows a cog wheel on top right. Click it and select “view log.” You can also open the devtools for the UI when on the calendar page.

I just checked the logs and nothing is printed here on any log level, probably only sync process logs are shown here...
I don't know why I get the single event popup and not the one for repeating events, but that is probably why the save can't be processed.
