Resignation

Hi, My employer is in Bangalore and my native in Tamilnadu, Due to Covid, i was doing work from home. and I am scared to travel again back to bangalore. But my employer is forcing me to travel back to bangalore and report to office. So, I gave my resignation letter. Still my employer is forcing me to serve notice period and asking me to report to office, I have submitted my resignation letter on 10th June 2021, and asked my employer to give me permission to continue my work from home till the completion of service period. But today i had received message like "you don't have permission to do work from home and your work from home will be considered as LOP". And they will consider salary after i returned back to office. But considering my health and family situation, I don't feel safe to travel back to bangalore. I have company properties like laptop and sim card. Can I leave without continue my service period and will handover the assets to them? Can employer take any action against me? or force me to continue my work? I don't want get a bad note in my carrier profile. Please advice
