Imagick处理PNG文件时抛出异常的问题求助

大家好，我正在基于Imagick开发缩略图生成系统，目前JPG和WebP格式的图片都能正常生成缩略图，但处理PNG文件时总会抛出异常，错误信息如下：

"improper image header `/tmp/magick-fj49nThGt9uvW0CFbLJj7XGsqT7x30OC' @ error/png.c/ReadPNGImage/4107 => /var/www/html/Dullahan/thumbnail/Application/Generator/ImagickThumbnailGenerator.php => 89"

对应的调用栈信息：

[
    {
        "file": "/var/www/html/Dullahan/thumbnail/Application/Generator/ImagickThumbnailGenerator.php",
        "line": 89,
        "function": "readImageFile",
        "class": "Imagick",
        "type": "->"
    },
    {
        "file": "/var/www/html/Dullahan/thumbnail/Application/Generator/ImagickThumbnailGenerator.php",
        "line": 54,
        "function": "generateThumbnailFile",
        "class": "Dullahan\\Thumbnail\\Application\\Generator\\ImagickThumbnailGenerator",
        "type": "->"
    }
]

有没有大佬遇到过类似的问题？麻烦帮忙分析下可能的原因，比如是不是PNG文件本身的格式问题，还是Imagick的配置、版本存在什么坑？
