Hi there.
For the plug-in to work with 4.25, you need to download the 4.25 version from the epic launcher. That’s the best way.
if you’re not able to do that, there is one other way, but you will need to have visual studio installed on your computer.
first copy the plug-in from the unreal 4.24 folder to the 4.25 folder, in the same place (your unreal 4.25 folder /plugins/marketplace/assets cleaner)
Then can use notepad to edit the .uplugin file andcand engine version from 4.24.0 to 4.25.0
then launch your project and it will tell you you need to recompile. Say yes, and hope it works.
Please note that I cannot guarantee the plug-in will work correctly if you choose to do it this way. The recommended way is to use the launcher to download 4.25 version.
Hope this helps
