UPDATE December 7
Hey all - the fix for this is in Zwift game version 1.32.0, which just released. Please update at your earliest convenience. This fix specifically targets PC’s with lower RAM specs.
This bug was difficult to triage and fix because we were unable to reproduce it internally. We synthetically created circumstances that led to this crash on our test machines, and 1.32.0 resolved them. As noted in this thread - some Windows machines with 8GB did not crash, while others did.
We had one person report that installing 16GB RAM solved this issue.
Please let us know either way if this is fixed or not for you. Thanks.
