[2020] Aim down sights bug (please help me)

I am experiencing a ADS HOLD glitch where I get kicked out of my zoom, its very frustrating to try and peak and hold angles this way. Is there a common fix!?? I assure you it is neither my computer or my mouse. I have tried switching do a different display mode but this only worked for a few weeks hence this post LOL please guys any type of advice would be nice.
