Various Run errors - Help needed

[noto10]

I installed using pip in Python 3.13.0 for Windows. Installation went well without errors. However, I get the following errors when I tried to run it:

Can anyone help?

I encountered this error and the issue was that I didn't have OpenSLL libraries in my path. Note that the bitcoin lib is using an older version of OpenSSL so you can't just download the latest OpenSLL lib and use that (it's a completely different name than the lib's listed in this line "File "C:\Program Files\Python313\Lib\site-packages\bitcoin\core\key.py", line 27, in
_ssl = ctypes.cdll.LoadLibrary(
ctypes.util.find_library('ssl.35') or ctypes.util.find_library('ssl') or ctypes.util.find_library('libeay32')
)")
I also downgraded my python version to 3.11 (but I don't think that had anything to do with the above issue)
