Failed to update snapshot in repository

Elastic Stack Elasticsearch
1

I have a cluster that has 3 masters, 2 hot, 2 warms, 2 colds nodes. I am trying to take a snapshot but I got this error;

"type": "snapshot_exception",
  "reason": "[cul-backup:cul-snap-2022.03.28-xxxxxxxxx/xxxxxxxxxx] failed to update snapshot in repository",
  "caused_by": {
    "type": "repository_exception",
    "reason": "[cul-backup] concurrent modification of the index-N file, expected current generation [1] but it was not found in the repository. The last cluster to write to this repository was [_na_] at generation [-1].
  "stack_trace": "RepositoryException[[cul-backup] concurrent modification of the index-N file, expected current generation [1] but it was not found in the repository. The last cluster to write to this repository was [_na_] at generation [-1].]\n\tat org.elasticsearch.repositories.blobstore.BlobStoreRepository.ensureSafeGenerationExists(BlobStoreRepository.java:2445"

I am using Shared file system that is Type: “fs” and snapshot data is being created under the path.repo successfully;

ls /mnt/data/sharing/es_backup/cul_snapshot/    
indices  meta-xxxxxxxx.dat  snap-xxxxxxxxxx.dat

Also, Repository Verification status is connected for all cluster's nodes

I have also deleted the repository and recreated again to solve this issue but it didn't work.
How can I solve this issue?
