Using VPet problem solutions / compilation to see the exact cause
Here are some solutions to common problems, other VPets that are fault tolerant have tried to be fault tolerant themselves
If you can open it before, but now it won't open, you can try to close the mod/reset the archive through the VPET problem solver - Setting Editor.
If your computer has poor performance, the first time you start up or update the animation, the cache generation will indeed be slow, please be patient!
If you have a bad internet connection, or are playing Steam Workshop, or are just unlucky, you may get stuck here for a while, I sometimes get stuck here for 1-5 minutes when I'm writing my own games, it's usually caused by internet fluctuations.
If you don't use the Creative Workshop mod, you can double-click the logo to skip it.
(It also works on Win10/11 with effects turned off, but it's usually a Win7 problem)
You need to turn on all animation effects in your system
Control Panel - System Properties - Performance. Activate the options "Enable desktop compositing" and "Use visual styles on Windows and buttons".

It's hard to fix bugs without error messages and locations, so if you're a little computer savvy, you can try manually compiling the VPet source code yourself to see if there are any problems.
