To install I downloaded the Windows version (7z) and extracted it to a folder with 7-Zip (also tried winrar) and ran /bin/freecad.exe

I have found I can open and use Ondsel if I disable my internet first, then it launches without issue. 

Note I have also tried the weekly build and have the same error.

by turning off the Internet, I can enter the application, but when I click on a link inside the application (with the Internet still turned off), I receive the same error and the application turns off (crashed). edit: I have the same problem in Freecad 21.2 BIM Workbench -> Help -> Bim Tutorial

we should redirect this error to freecad repository, because this is internal error.

Update/Fix, I had an environmnet variable "SSLKEYLOGFILE" set which is used for capturing SSL certs to a text file to allow packet capture and later decryption of captured HTTPS data. Apparently OpenSSL as used by Ondsel doesn't like this, not sure if it allways doen't like it or just because my SSL cert log file was big (like 3GB).
