I have installed both the extensions:

Answer 1

After installing these two extensions at the same time, I can reproduce the same issue.
The root cause of the issue is that terraform install task exists in both extensions at the same time.
Their simplified version of YAML task names are all TerraformInstaller#0.
To solve this issue, you can uninstall one of the two extensions.
Or you can specify the full name.
For example:
- task: ms-devlabs.custom-terraform-tasks.custom-terraform-installer-task.TerraformInstaller#0
OR
- task: charleszipp.azure-pipelines-tasks-terraform.azure-pipelines-tasks-terraform-installer.TerraformInstaller#0
