[2025.31550, Windows 11] Engine COMP Fails To Launch

Hi @dylanroscover - thanks for the report. Strange it started working as others still see it in the current build. Perhaps another issue. We’re looking at a potential fix.

If it shows up again you could create a .dmp file for the hung TouchEngine process and we can confirm if it is the same issue.

Thanks to @SAT_Innovation we’ve identified one cause of this as having MIMALLOC_DISABLE_REDIRECT=1 set in your environment variables. This may have been done if you’ve previously had issues importing some Python libraries, such as in this thread. Could you please check your environment variables to see if this is set, and try setting it to 0 (or removing it) if so.

We’ll look at fixing the issue which stops TouchEngine working when this is set.

This will be fixed in the next build we release, so TouchEngine will continue to work when MIMALLOC_DISABLE_REDIRECT=1 is set. In the meantime, setting that environment variable to 0 or removing it should solve the issue (if you don’t need to use it for other reasons).
