RAD pack(LITE) launch problem

I go on Version > Modpack > install RAD pack(LITE), launch minecraft but when i join the game i have : craftstudio API: Requires version 1.0.0 but mod is not found on client.
How i that possible ? when i go on curse RAD Lite it doesent use craftstudio... i dont understand !? aternos install a mod that is not in the mopack !?

And u cant check what mod is installed on the server or i dont find where

(sry im french)

i found this on the historic:

but nowwhere i cant this "craftstudio API", why the server claim it ???

i tried to install on my PC 2 version of craftstudio and that does not solve the problem...

Are you using the same version of the modpack that is on the server?

i took the version on twitch rad lite 1.2.
