Moving mouse left and right is super fast and up and down is super slow

clientside lua startup!
Lua JIT is DISABLED!

it says that after hosting for example a sandbox map but it’s super frustrating… when I move the mouse left and right it’s super fast and up and down it barely moves, tried reinstalling via deleting local content via steam and it didn’t solve it also ticking and unticking every possible option under “mouse” tab didn’t do anything. Please help.
