Likely an WebVM issue with syscalls. That is normal, but still should be fixed.

Thanks for the report. The initial issue has been fixed and deployed (though due to CDN caching it might take some time before the new version is visible everywhere). There is, however, another issue further up in the execution that we'll continue working on.

This problem should be fixed in CheerpX 1.0.9 and the currently deployed version of WebVM. Consider joining us on Discord (https://discord.leaningtech.com) for further discussion.
