Describe the bug

I can't install any modpack in 1.16.5 "due to an unknown error". I even tried to upload a modpack from a .zip file, to create an new on from scratch, nothing worked. The first modpack I had the issue with was Sky Capsule Project but after several test it is with any kind of 1.16.5 modpack.
The download fails at 0% really fast (after like 3s)
Btw I can download and launch any other version's modpack

Steps to reproduce

Just try to download any 1.16.5 modpack

Expected behaviour

I expect to download the modpack
