An unexpected error occurred (file '', line , function '')
Hi,
After installing on several devices and noticing that some returned errors while others didn’t, I compared the system information of each one and found that the issue, in this case, is related to AVX CPU extension support. One of the VMs didn’t inherit this extension from the host, and once it was enabled, the error disappeared.
We can conclude that the error is related to CPUs lacking the AVX extension.
Best Regards.
