Maya 2020 uses an old version of OpenSSL that leads to crashing on 10th (Ice Lake), 11th (Rocket Lake) or 12th (Alder Lake) generation Intel CPUs. The problem occurs when import wingdbstub
is reached, crashing Maya completely.
There are two ways to work around this problem:
1) Make sure you have Wing 8.3.2 or later. Then uncheck the Debugger > Network > Use Digests to Identify Files
preference in Wing. This turns off a part of Wing's debugger implementation that calls hashlib
, and thus
avoids the crash.
-or-
2) Set Windows system environment variable OPENSSL_ia32cap
to the value ~0x20000000
before starting Maya. This disables the OpenSSL feature that is leading to the crash.
Are you able to generate a debug log file by setting kLogFile in wingdbstub.py to a filename? If so, please send a log from a connection attempt to support@wingware.com. Note that wingdbstub.py files are specific to the version of Wing used, so make sure the one for Wing 8 is used when trying to connect to Wing 8 (and likewise for Wing 6 & Wing 7).
