Hi Thomas,
Have you tried running the actions as a different user? The actions use the security context of the user running the browser, so you might have to run the browser as a different user which has sufficient permissions. This article also covers that: https://www.lansweeper.com/knowledgebase/running-actions-as-a-different-user/
If that doesn't work, it's best you
contact our support team. They can ask for additional details which might give an indication of the cause.
All I can really suggest is making sure you have an updated browser and the latest extension.
