Type Tool deselects itself after a second and goes back to previous tool when shortcut used

[halilk1262456]

15.1.2 user here. Windows 10 pro. Have a decent cpu, gpu and ram.

Deleted preferences, re installed the application several times but this bug does not go away!

For the small indd files this problem do not occur. But with big sized files like catalogues this constantly happens. 

When i press "T" key shortcut for type tool, cursor becomes type tool for max 1 second and goes back to

previous tool. It works if i go and select with mouse from toolbar. 

It looks like this is lasting problem for several years.

It is really frustrating for works require fast approach.

Can someone from Adobe help?

Did you follow these steps?

Yes, but like i said in the beginning, it only occurs in big sized projects.

I have re installed the app many times. It's in my local ssd.
