im having an issue with this mod,when i try to launch mc with this mod,when mc opens,it says this,do you need crash text?

could you provide:

• mc version, forge/fabric?
• name of the file you downloaded
• other mods you have

you can also add crash test

mc version is 1.19-forge-41.0.99
file name : zergatul.freecam-1.2.0-forge-1.19
i tried with mod and without any mod,its not changing,also i tried those versions of this mod and its same= -
zergatul.freecam-1.1.0-forge-1.19
zergatul.freecam-0.2

ah i forgot the crash test. there it is
---- Minecraft Crash Report ----
// Uh... Did I do that?

Please check 1.2.3 version on curseforge

thanks that worked.
