Css not loading after installing the apps like helpdesk, crm

It’s really frustating, there is no proper solution anywhere, and they claim it as open source. No proper doccumentation either. For the last one month i am trying to fix the CSS issues, whenever i am installing the apps complete css goes away.

i am running my ERPNext on docker, I installed the apps both in frontend and backend for eg i tried to install helpdesk app

bench get-app helpdesk
bench --site frontend install-app helpdesk

after this i restarted my containers, also did bench migrate and restarted again.

As soon i login to the desk, there is nothing showing complete broken page with no CSS, I have seen some solutions in internet but none of them worked here what i tried

bench build --hard-link --production in the frontend. this doesnot work either. Look at the image bellow.

I really request an working solution for this, I know 100s of people are stucked at this point of time. It would be great if someone can help me in this.

Please review the Nginx logs and check the permissions on your Bench folder. This should provide insights into the issue. I hope this information proves helpful

These are the logs
