windows 10 – Win10 startup crashed / Drive with Bitlocker unable to repair

I have a laptop (T14) with Win10 installed. Recently, it crashed and on startup it automatically goes to repair mode.

Drive is locked with Bitlocker (I have the key available). So when I log in I try chkdsk which doesn’t work as it says the drive is in readonly. When I try to clean attribute it tells me disk has errors and I need to repair them first for attributes to be cleared.

I tried with USB with win installation on them. I cannot do format because the drive is locked with Bitlocker. I tried to suspend it but was unable, it returns error.

So I am open to any solutions, repair the existing windows, formatting the drive… anything I don’t mind just to get it up and running. Thx!
