I am so sorry that perhaps it was caused by robots.txt and yet you assisted me. I am so thankful to you.
Thanks for your guidance and paitence. Hopefully the issue will be resolved. I have added above mentioned rules into my robots.txt which was escaped by a developer, hired previously. Than cleared cache. Also i have resubmitted into search console.
I tested url half hour later in search console, yet its showing broken site and scripts are not loading. Screenshots hereby:

I have scanned my website with wordfence which is showing some recently modified css and js files. See screenshot hereby https://prnt.sc/1e4r465 .Maybe this could be the cause?
