YaST broken after removing PCRE 7.9

I installed PCRE 8.12 on my server using YaST but found that PCRE 7.9 was still installed and active (as seen via pcretest -C). In order to delete or deactive PCRE 7.9 I tried deleting it using YaST. But I think that process deleted many other files which were needed for YaST to properly run. Now, YaST is broken. When I start YaST in my terminal and select+enter 'Software Management' or any other option, error like following appears:

# yast
