Then still, there are some other errors somewhere, that might be triggered by having unequeal sized partitions sdb1 and sdc1 You could look at backports w.r.t. 32-bit vs. 64-bit, maybe related to changes 512 sector sizes and 4k page sizes. And better use gdisk instead of fdisk I think. And maybe check first 1MiB and last 2MiB of both disks. There are also Ubuntu 32-bit and 64-bit images available for RaspberryPi's with kernel 5.3.x, maybe that gives hints where the root-cause is.
