Knime missing nodes after i download the workflows fronm GITHUB

Hi,

I have 2 problems related ad lost all my work, please help.

Few month ago, i had a replacement laptop at my work, hence i copied all my workflows to Onedrive and also uploaded few of the workflows to GITHUB. On my new Laptop, i have installed a different version of knime.

Today I want to execute a workflow and had to pull the code from Github to my knime workspace and when i open the workflows, in one of the workflow, many nodes are missing, in my second workflow, i can see some nodes missing

So i tried to get the code from One drive and i cannot find my workflows n teh OneDrive

please help here
