Unable to execute package after removing AttunitySSISOraAdaptersSetup software

I am using SSDT 2017 version 15.9.13.

Recently i have uninstalled oracle provider by attunity.

After that, i am not able to execute my package, getting error like below

Failed to start package, Additional Information: Exception deserializing the package 'Value does not fall within the expected range'(Microsoft.DataIntegrationServices.VsIntegration)

I am using project level connection mangers, if i remove those and create at package level, than i am able to run the package.

But i need to use project level connection managers.

How to solve  this issue.

Thanks in Advance.
