为了从 SVG 导出 PNG 我下载了两个软件
为两个可执行文件创建了 shim
shim_exec “inkscape.exe”
shim_exec “magick.exe”
然后觉得 inkscape 不好用，卸载了它，此时 shim 指向无效的地址
再执行 magick icon.svg -background none -resize 1024x1024 icon.png 进行转换时
magick 会尝试在一些目录（包含 PATH）中寻找 inkscape.exe，然后触发错误
PowerShell 7.5.1
PS G:\> magick icon.svg -background none -resize 1024x1024 icon.png
ERROR - Shim application path does not exist.
Shim is no longer valid and must be regenerated.
PS G:\GitHub\shared-config\packages\astro-developer-pack> mm
mm: The term 'mm' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

The most similar commands are:
> gm, mi, mp, mv, rm
PS G:\> magick icon.svg -background none -resize 1024x1024 icon.png
ERROR - Shim application path does not exist.
Shim is no longer valid and must be regenerated.

at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state)原因是 ImageMagick utilizes inkscape if its in your execution path otherwise RSVG.

实际上此时把 inkscape.exe 换成任意可执行文件都会被执行，比如 calc.exe，很容易攻击
