Socket hang up after certificate change

I get socket hang up when I change certificate under Settings.
I do a simple GET for https endpoint. It worked with certificate 1.
Then the only thing I did was that I changed the certificate and key files under settings - and I get socket hang up.
I tried putting back the working certificate 1, but still socket hang up.
Doing GET with other tools works fine.
Problem occurs after certificate change (both certificates are fine and work with other tools).

Postman version 10.6.7
Windows 10

Once I reinstalled postman and then when I put certificate first time, it worked. But when I changed certificate again, again socket hang up.

It isn’t realistic to reinstall postman every time I want to change certificate.
What could be causing this?
