'UiPath.Core.Activities.AsyncNativeActivity' from assembly 'UiPath.UiAutomation.Activities

[Rahim_Bhatia]

Hello. I need help resolve an issue that I am getting in my workflow. My code was working properly and recently started giving me an error. I have tried to upgrade UiPath.UiAutomation.Activities and also tried downgrading to see if that resolves but no luck. Also tried upgrading UiPath studio version but still giving the same error and at this point not sure what is the issue. The issue happens right at the start when it hits InitAllApplication (REF)

Invoke InitiAllApplications workflow: Could not load type ‘UiPath.Core.Activities.AsyncNativeActivity’ from assembly ‘UiPath.UiAutomation.Activities, Version=23.10.9.0, Culture=neutral, PublicKeyToken=null’.

Any suggestions that can resolve this would be greatly appreciated

Thanks

Hi @Rahim_Bhatia

Please check the below threads:

Could not load file or assembly 'UiPath.Activities.RuntimeGovernance

Thank you for providing me with the extra files. Unfortunately, indicating an element from the Attach Browser activity did not cause any errors for me Could you maybe do these steps to clean your environment a bit: Close Studio kill the UiPath processes in the task manager clear (or simply rename) these paths with temporary cache files%USERPROFILE%\.nuget %LOCALAPPDATA%\UiPath\.cache %LOCALAPPDATA%\NuGet %LOCALAPPDATA%\Temp\NuGetScratch %LOCALAPPDATA%\Temp\nuget start Studio and …

Hi @p.kertai, Even though if you reinstall the UiPath, the system cache remains the same and may cause the same error. So, can you try to restart your system? and try to reinstall the package. Regards, @90s_Developer

Could not load file or assembly 'UiPath.Excel, Version=2.17.0.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified

Try first to upgrade all dependencies to the latest version in the project. Close Studio. Go to the folder where the packages are downloaded → %userprofile%\.nuget and rename the packages folder to packages_backup. Reopen the Main.xaml or project.json in UiPath Studio. Let us knot if this helped.

Most probably you have issues in that Studio/Robot machine and cannot install the UiPath.UIAutomation.Activities.23.10.9 from https://pkgs.dev.azure.com/uipath/Public.Feeds/_packaging/UiPath-Official/nuget/v3/index.json package source.

Check this aspect in the Studio logs. (Ctrl+L)

Hello. Thanks for your help. I tried the solution that you mentioned and the error still remains. Any other suggestions?

Hello. I have the latest package installed for UiPath.UiAutomation.Activity (23.10.9). Also rename that backup file so it installs new file and error still remains

What is your Studio version? Is 23.10.4?

For the process and for your custom library if you have one, can you republish by disabling the Separate Runtime Dependencies?

Go to Studio Machine → Start → UiPath Diagnostic Tool → Activities Issue → collect everything → provide the zip file

Open a powershell.exe console, run the below code and provide the results:

Write-Host "`r`n**********`r`n"
Write-Host " System variables:"
[Environment]::GetEnvironmentVariables("Machine") | Format-Table -Wrap -AutoSize
