    • Relaunch UiPath Studio and check if the issue persists.
  2. Restore or update project dependencies
    • In UiPath Studio, navigate to Project > Manage Packages.

First try under the namespaces add the System.Collections.immutable. After adding this try still doesn’t work then do follow step
Try by simply restarting the studio and your machine.

Sometimes this will works.

Initially it didn’t solved my issue and then I downgraded the form.activities package version that I was using and the issue got resolved
Thank for your suggestions
