Found recently that Dimensity has patch v1.2 which also repairs issue, so not need add it into DEP ignore, if patch installed. But workaround may still help out other (not repaired) applications.
Installed Dimensity, Started game and it crashed (exception code 0xc0000005). Following steps did the trick:
1. Check “Turn on DEP for all programs and services except those I select” box under Data Execution Prevention
2. Add path to DimensityPl.exe to exception list.
I think, these steps may help out also for other applications which have DEP issues.
Not tested with x86, but probably works.
