Question: Double shift in 2-D math

I have been experiencing an error in the 2-D math text in Maple 2021. Every time I use the shift button the command seems to double. So if I for instance want to define A:=2 it will write; AA::==2 making the command useless. This only happens in 2-D math.

I have tried restarting Maple, my PC and uninstalling then installing maple 2021 again but nothing changes. This error appeared after updating maple the 6th of january 2022 to Maple 2021.2. I have a MacBook Air M1 2020. 

Please help as I have an exam soon
