It's "Windows 10 x64-0-s001.vmdk" which is missing.

According to the screenshot, this is an additional virtual disk, which does not seem to contain data and has not been touched since 2021 anyway!? In that case you may either remove that second virtual disk from the VM's configuration, or replace the missing file with a copy of e.g. "Windows 10 x64-0-s002.vmdk".
