Hi,

合入上面的改动后，能否试一下把FRHIBreadcrumbNode::WalkOutRange里的while (true) 改成while (Leaf)，然后在试试是否还崩溃？

好的我本地抽空试试

Hi,

如果后续有结论，麻烦再同步一下，感谢。

Hello!

We are having the same issue. In the steam build while enabling profilling and RHI_USE_RESOURCE_DEBUG_NAME in the Test build.

Making the while (Leaf) change made it crash at a later date than before. Or it might just be a coincidence.

Could you upload the log or callstack? (If you couldn’t upload in this case, please create a new case and provide the detailed info.)​
