CloudFormation Lint Version

cfn-lint 1.3.0

Windows 11

Describe the bug

After updating from v0.87.7 to v1.3.0 i noticed a new finding, which is a false-positive:

  SecurityGroup:
    Type: AWS::EC2::SecurityGroup
    Properties:
      GroupDescription: "Security Group"
      VpcId: !ImportValue VPC1-VPC-ID
      Tags:
        - Key: Name
          Value: 'SecurityGroup\'

[cfn-lint] E3024: 'SecurityGroup\\' does not match '^([\\p{L}\\p{Z}\\p{N}_.:/=+\\-@]*)$'

Expected behavior

cfn-lint does not provide this false-positive finding. I think the regex might be wrong, but regex is not my speciality.
