Modpack saving as generic file

[Dangerabbit]

Describe the bug

Whenever I save a mod pack it just saves a generic file instead
For example, if the mod pack I tried to save is called EXAMPLE then it would save as a file that is just EXAMPLE with no file type or data inside

Steps to reproduce

1. Press Export mod pack
2. Press Export
3. Choose folder (for example downloads)
4. Press save
5. Go to folder
6. Find empty file

Expected behavior

It should just save as a .mrpack file with data inside

Your instance likely has : in its name, causing Windows to think Modrinth is trying to write to an alternative stream of that file.
