As per the log and initial investigation, it seems NWjs is crashing, to
confirm the issue I have posted this behavior on NWjs gitter "
https://gitter.im/nwjs/nw.js" Refer to the below screenshot:

It seems that some of the third-party libraries cause the NWjs(pgAdmin4
) application to crash. The difference between 6.2 and 6.4 is, we have
released 6.2 with Python 3.8 while 6.4 with Python 3.10 that could be the
issue here. I checked https://www.python.org/downloads/windows/ and it is
clearly mentioned that "Note that Python 3.10.0 *cannot* be used on Windows
7 or earlier."

Give us some time I am not sure what could be the solution at the
moment.
