Your modpack download is not a valid archive file. The ZIP header looks broken. What program are you using to create the ZIP archive? Try recreating it. Make sure you are incrementing the pack version number any time you change your modpack download.

im using winrar but i also tried using 7 zip, both times it didnt work out.

i also tried to change the modpack version number like you said, but i dont think that is the problem.

Something has changed. Every time I download the file manually it works as expected and I get a working file. I have added and removed the pack from my Launcher multiple times without no issues.
