Hi again @bensan.morris,
The symbol server is actually up to date. The file you need would be
https://driver-symbols.nvidia.com/nvoglv64.dll/64af3e20428d000/nvoglv64.dll
(I just downloaded it with wget)
Sadly the webview of the directory is not correctly refreshed at the moment.
The directory name is a combination of the official file timestamp and the file image size in lower case. If you download the official driver .exe file and extract the relevant file, you can check the details with dumpbin.exe /headers nvoglv64.dll.
Filtering the necessary data gives:
64AF3E20 time date stamp Thu Jul 13 02:58:24 2023
428D000 size of image
The timestamp above is GMT+3, so I suspect there is some issue with how Visual Studio gathers the directory encoding from the file time stamp. Because your timestamp seems to differ (which would translate to 64AFF4D8 instead) and might cause the issue.
