Problem with previous landlord AFTER releasing security deposit

Hi,

I have some old problem with previous landlord coming back to me recently.

Long story short,

* I moved from my old apartment and signed the “state of the apartment check” on 08.Dec.2023, with some notes that somethings needed to be check, then, my landlord hold my deposit.

* I asked my Fire insurance to stop the insurance on that apartment on 08.Dec.2023, and start with the new apartment. Latter, I just knew that it means, effectively, the insurance for previous apartment only covers up to 07.Dec.2023

* My previous landlord reported the damage on 15.Dec.2023, sent me invoice, and at the end we agreed to release my security deposit minus this invoice (which is about half of my deposit). We agreed on 06.01.2024,  and I already received part of my deposit. I didn’t know (I just know recently), if I keep my previous fire insurance to cover a bit longer, probably I could claim it. But, ok. I though, I closed out that problem and start fresh in the new apartment.

* Recently, her insurance contacted me that apparently, they did another check on March/May 2024, and said that I may be liable for damage reported 15.Dec.2023, but for another reason (apparently the previous damage assessment because of wrong reason). Her insurance asked me to contact my insurance (because seems like it has a major consequence), but my insurance said because the damage was reported after the end of the coverage (and also said it is minor, seems like they did not take into account the note in the “state of the apartment check” about the fact that it still subject to check).

* I wonder, where do I stand in this issue (including from the legal perspective). What should I do? This is really bothering me and takes too much of my energy

Any input will be appreciated,

Regards,
