I have been trying to create a private modpack using the Technic launcher and every time I try to launch it the loading bar at the bottom will say "downloading minecraft assets" for less than a second and then disappear without launching the modpack. Is this a mistake on my side with something I overlooked when making the pack or is this a problem with the Technic launcher itself and how do I fix this?
I would suggest pasting the launcher logs. Documentation usually helps folks around here fix things much faster than if such resources were unavailable to them.
Thank you
