Currently, there is no known way of breaking BitLocker by brute force. If you are the one who created the Bitlocker Drive, you can use the 48 Digit Recovery key that was given to you upon creation or if you linked it to your MS account, the key might be there. If you are not the owner or haven't stored the key/linked the key to your MS account, just give up and do what Mac said. In the case of windows 11, if Bitlocker is linked with the TPM + PIn/usb... it can't even be brute-forced.
If you still want to try tho, some windows PE like strelec or hiren have tools inside to try to brute-force a BitLocker drive. Have a go at it.
