Hi@Dhinesh28R,
Could you please tell me that:
If you have ever edited the app and try to run the app without publish the version that you have edited?
Generally, if you have updated the app but not publish it, PowerApps will try to run the old version that may cause the load error.
In addition, please consider take a try to turn off "Delayed load" option and "Improved app rendering (final validation)" option within Advanced settings of App setting of your app, re-publish your app, check if the issue is solved.
If the above could not solve your problem, please provide more details.
Regards,
Qi
