You can try downloading the previous version and see if it works. I've provided the steps below:
- Make sure you uninstall Paint 3D first.
- Visit https://store.rg-adguard.net/
- Paste the URL https://apps.microsoft.com/detail/9nblggh5fv99 and generate the AppX download links
- Download and install the older Paint 3D version (try version 2310.24037.0) Download the one with .appxbundle
5. Disable automatic app updates to prevent it from updating
Let me know if it helps.
