Different Storj versions for 2 nodes (v1.34.3 vs v1.24.4)

Please, remove all Watchtower instances:

Then run it back: Software Updates - Storj Docs
And as @baker said - please update the storagenode manually ASAP: Software Updates - Storj Docs

Regarding upgrade of the Docker desktop - if you plan to switch to wsl2, then - yes.
