Affinity Publisher files are all becoming corrupt

[RedLorrYellowDesing]

Unfortunately all of my Affinity Publisher files are all becoming corrupt, I can fine a common link, is there a limited files that affinity Pub can handle?  I love this product but this is making it impossible to use because when i make a document it becomes corrupt a few days or weeks later.

Do you save the .afpubs and images locally - or on a network or cloud? Do they appear as corrupted after their first save and re-open action – or any time later?
Could you upload such a corrupted .afpub?

I currently store the file and associated linked document in a file stored on the cloud, Pcloud to be exact. it becomes corrupt a few days or weeks after creating. 

I am unable to upload the file as its over 512mb, thank you for your help.

Possibly this cloud or your computers connection/communication with the cloud is involved in the corruption.

Can you save an .afpub from within APub locally and re-open it to see if the corruption still occurs?

You titled "all files become corrupted" – so you could upload an affected .afpub which is a lot smaller than your 512 MB document, may be a new (nearly empty) document which got saved into that same cloud.

I would definitely try a sample file with another provider pcloud has caused problems in the past
