Azure Synapse File cannot be opened error

Question

We are trying to query data from an Azure Storage Account in an Azure Synapse Workspace through a SQL serverless built-in pool. This worked fine till yesterday when we got the following error File cannot be opened because it does not exist or it is used by another process with a link to the following Microsoft Documentation: LINK .

Today we investigated the error and tested the following things:

• With a different account we are able to run the same SQL script.
• In a different Synapse workspace we do not have any problems.
• All accounts are in the same Active Directory Group, so they all have the same access.

When we explored the Synapse workspace we found the Monitor tab and at the moment the error occured there are three failed SQL scripts. All the scripts have the same error: Error handling external file: 'waitIOCompletion error. HRESULT = 0x80070003(offset = 0, bytes requested = 117621).'. Error handling external file: 'waitIOCompletion error. HRESULT = 0x80070003(offset = 0, bytes requested = 117621).'.
