Hello
We have pretty big app with about 20 forms and 35 tables and views from Sql Server
and with data caching for offline mode (using SaveData, LoadData).
Last time the app was modified in May and it worked fine then in Studio and currently published version works correctly.

But when I tried to open the app in Studio it opens the app about 15min (before was about 1 min).
After first opening it shows message that schema was changed for some tables and suggest refresh and reload (but nothing has been changed in schema).
After reloading it shows me huge amount of errors - 1500.
So it looks like there were some breaking changes between v 3.20023.8 and v 3.20073.28.
But I have looked through Power Apps and couldn't find what changes might cause such problems.
Most error are related to collections loaded from tables and looks like follows:


So it doesn't recognized correctly collection created manually or loaded from Data Sources - but not for all collections, most of them show no errors and only several with errors.
I have tried to re-add data source, tried in different browsers but still couldn't resolve or identify reason of this problem.
Does someone else experience such problem with Studio?
I would appreciate any help on this problem.
