so today i was playing payday 2 on steam, and the default keybind for running is shift. so i usually hold down shift 24/7 while playing, and after i finished the round the key wouldnt work. it persists until now.

processor; intel[r] core[tm] i7-7700hq cpu [at symbol] 2.80 ghz 2.81 ghz

system type; 64 bit

installed ram; 12gb

also this issue only presists on my left shift key, i can use the right shift but it is very uncomfortable
