Employer threatening me that now his lawyer will talk to me

Yesterday my employer threatened me that now his lawyer will talk to me. On 26th of August 2022 I put resignation and I mentioned that I will not be able yo complete the notice period and I am ready pay for the damages. But they are forcing me to complete the notice period. Yesterday I was working on two projects I made some changes but I haven't them yet and due to that websites stopped working. After making changes I gone outside because some fight was going on. When i came back i was not able to access anything they removed all the access from me. After that I called project manager and he said he will do something. After some time I again called him because I haven't got any reply then he said to call the director then I called the director and he said that I had made some changes due to that websites are not working then he said that now my lawyer will talk to me. After that he said to me that you can talk to your project manager. Then I called my project manager and explained the whole problem then he said that today HR will tell me. Now Iam worried what should I do next.
