Hello
When I start the program, I receive a message: [0x7FFC47E1ACB0] ANOMALY: meaningless REX prefix used.
How can I fix the error?

Never seen this issue before an searching for the error message comes up with a wild flora of suggestions, from faulty Windows drivers to problems with anti-virus software...

Can you show a screenshot, to get an idea of how it appears (in a textbox or system message or what)?

The message appears only when I start the multiprocessor parallel.
Computer characteristics: 64-bit processor, Intel Core i5 11 gen, 4 nodes, Intel Iris. Maybe it's all about the video card?

Might be. Regardless, do I understand correctly that you are able to run the calculation without problems? It looks more like a debug message than a real error.
