Downloads are slow after reuse

When I first started using it, it was very fast to download, and it was okay to burn normally. There was a time when I disabled extensions. There are a lot of problems when I open it again later, I tried not being able to initialize, there is no valid python. The biggest problem now is that I can’t download it at all, who can help me

Delete the whole C:\Users\<user>\.platformio directory and restart VSCode. It should redownload everything. Keep an eye on the task manager for network and disk usage.

It didn’t work, I’ve tried many times.Thanks for your help.
