I'm glad you reported that. I tried again & it crashed, and I found for
sure what happened this time. Fixed in next beta.

the second case:

The crash was intermittent for me, but I think it was caused by
uninitialized memory. I reassigned the internal character codes and
the uninitialized memory suddenly became meaningful. I have fixed
that problem for the next beta. I hope that is what you were seeing.

This last line crashes J, why?
JVERSION
Engine: j902/j64/windows
Beta-c: commercial/2020-07-20T15:00:44

Apart from that, after updating base library from version 9.2.3 to
9.2.4, it still gives (in package manager) Installed 9.2.3 and
Latest 9.2.4
I do have administrator rights.
