Unity editor won't open for this project with packages

I’ve been testing out a few packages, they are fairly heavy (25MB 600 files) but my computer should be capable of handling them.

installing them, importing them into the project, and using them after importing them all went fine, absolutely no issues, but once I save the project, close out, and try to reload, the editor takes up to 15 minutes to open the project, stuck in either “assets” or “packages” phase of loading. eventually the loading window will just close, unity editor doesn’t pop up and doesn’t show up in background tasks on task manager.

projects with no packages are also taking a while to load, but not nearly that long, and they do eventually open.

I tried reinstalling unity but that didn’t change anything

something that might be causing this but I’m not sure and I don’t know how to fix it: unity’s program files are on my C drive (which is an SSD), the project files are on my hard drive. I don’t know where the package files are.
my license is personal, up to date, so that should be fine?

Yeah lake a look at a project Library folder some time. Huge numbers of little files getting read and written to, which is exactly the kind of workload old school HDD’s are terrible at even if the drive is defragmented, because each one of those little files requires the head to move position and wait for the right point in the platter to rotate in front of the head before the access can start. Repeat that over and over for the thousands of files. For example, in my current project the library folder contains 59,381 files. Put the project on an SSD. Also, if your computer has a low amount of RAM it can compound the problem by repeatedly hitting the swap file during this process.
