Hello yanbou893 ~ It's recommended to use english language for a better global understanding. However, I used a translator to understand your question, I hope my answer will help you.
If I understand you right, you deleted an IAM permission on your user in your GCP project which is restricting you to delete some resources? Depending which permission you deleted, you can add it back by following this documentation [1].
