adobe xd 2019 version 19.2.22.3 not working properly

I know my Question is sound silly but I am very new to adobe xd. I just have installed adobe xd latest version but it is not working properly, I mean when I am in the middle of doing something xd behave strangely (like ctrl + Z , Ctrl + S don't work and Hand icon does not show up when I press spacebar) but when I switch to other tab using alt+ tab and then come back to my project everything worked just fine.. I don't what is the problem because adobe xd 2018 version worked just fine but xd latest version is not working properly .it just got stuck when I am in the middle of doing something. I don't know whether its problem with my pc or whatsoever. I have searched online but nothing worked out for me. It will be really appreciable if you help me out. Thanks in advance
