How to debug or turn off dynamic code snippets #2013

In one of my runs, when executing the "shl dword ptr ss:[rsp+rcx*1-0x5D], cl" instruction, the cc_src in it is somehow equal to eip. This causes the calculated eflags to be wrong. When I tried to debug it, I found that the relevant code is dynamic code（Just like in the picture）. How can I debug the relevant code of unicorn? Should I look at the assembly of the dynamic code line by line, or is there any other better way? Sorry, this question may be stupid. 1727319023745 1727319629171

To add, I use vs2022 on windows and unicorn to simulate x86_64
