VMware Live Cyber Recovery 7.26.x and earlier
This is caused by a limit on the cache space, as vLCR will cache VMDKs on demand. In the case for large VMDK files, it will take a considerable amount of time. The UI has a predefined timeout of 60 seconds, which is not sufficient enough for larger VMs.
This issue is seen in VLCR versions 7.26.x or earlier.
Run the initial restore guest files workflow, wait for ~5 minutes after it fails, and then attempt again.
