Premiere 2022 issues opening project from network
I'm running Premiere 2022.2.0 on two Windows PCs with similar builds (PC1: i9/64GB/2080Ti/Win10) + (PC2: i9/32GB/3070Ti/Win11). Both are connected to my QNAP TS-1685 NAS via 10GbE switch for shared media. On each individual computer, I have no problems at all with this setup. Playback is smooth, relinking is quick, etc. However, when I save a project on PC1 and then attempt to open that same project file on PC2, the project loading screen hangs at 75% and loading will not complete. Some trial and error indicates that, if I unlink all media before saving, PC2 will eventually open the project but it takes hours and hours depending on the complexity of the project. If I don't unlink, the project never loads as far as I can tell.
This obviously has something to do with the networking but I'm baffled by what that could be. If I was direct connected via USB, the project file would open instantly and ask me to relink as usual. That would also be the expected behavior if there was some sort of mismatch in the drive mapping here so if that's the case, why is the project hanging indefinitely? It's making working on the two systems impossible.
Wondering if anyone using network drives (NAS or otherwise) has had a similar issue. I found an answer in the forums that suggested repairing Virtual C++ processes but that had no effect. Really struggling to identify the cause of this and could use some help. Adobe chat did not understand my issue and I haven't been able to get on a phone call with them but suspect that would be a dead end anyway. Really need both of these up and running!
