Hi @Sachinbansal ,
Could you please share a bit more about your scenario?
Do you want to turn off the "Use Column Display names" feature within your app?
Currently, within PowerApps, there are some updates on "Use Column Display names" feature and "Use GUID type instead of GUID string" feature:
"
Precisely what we have done is to remove the Preview switch for new apps and existing apps that already had it turned on, which has been the default for a while. If you have an app with one of these features already turned off, the switch will still appear so that you can turn it on. Once turned on, saved, and reloaded the feature can no longer be turned off but you can revert to a previous saved version of the app in the app portal. Someday we will force all apps to use these features but wanted to provide a grace period to minimize disruption.

Please check the following blog for more details:

Based on the error message that you mentioned, it seems to tell that the _objectid_type column is required to provide a GUID value, but you provide a string value.
In order to fix this issue, please consider take a try to convert the GUID string value into a GUID value using GUID() function. Please modify your formula as below:
Patch(
Notes,
Defaults(Notes),
{
...
_objectid_type: GUID("Your GUID String"), /* <-- your GUID string may be like '0f8fad5b-d9cb-469f-a165-70867728950e'. */
...
}
)
