R5: You have a bunch of unfinished 3 clues. If any of these extends to the right, it forces the corresponding 3 clue in R4 to the left. You can solve for all of the 3-clues in R4-5 this way.

R8: Same logic as R5 above to complete all the 3-clues in R7-8.

R14: If anything in C27-31 is black, it causes a contradiction in R13.

C41: Since C43 is all 1-clues, any attempt to place white in C41 R4-7 will result in a contradiction. These must be black.

R12: Extending the 17 clue past C27 causes a contradiction in R13.

R18: Extending the 4-clue will make at least one of R20C11 and R20C14 white, possibly both. Either way, it forces the 22 in R20 to nudge over into C36. (If only R20C11 is white, the first 2-clue still needs to fit to the right of it.)

C40: If the 4-clue is placed in R10-13, it forces the 4 clue in C41 down to the bottom 5 rows. If the 4-clue in C40 is not in R10-13, then it is forced down to the bottom 5 rows. Either way, at least one of these columns have blacks in R17-19, and this allows whiting out most of the rest of those rows since they already have blacks in C12-13.

LL solves from there, finally.

Some of the above may not have been necessary; I was taking notes as I went so I wouldn't miss anything later.
