Looker Studio data has disappeared

I’ve had many dashboards created in Looker Studio for a long time and I thought I made the switch correctly from UA to GA4 last year or so. But today, July 1, there is no data showing now for our Looker Studio dashboards. Anyone know how I need to fix this? I did notice there isn’t anything in the measurement ID section in the right column. I’m logged into Looker Studio under File/Report Settings. thx.

I did look in the trash bin but restoring one of my dashboards there didn’t bring back any data.
