Hello EDK2 community,

I have encountered a strange error. I am trying to activate source code debugging with the following changes:

I drew information from the following sources: https://raw.githubusercontent.com/wiki/tianocore/tianocore.github.io/OSFC/Debugging_UEFI_Firmware_Linux_Workshop_OSFC_19.pdf , https://cdrdv2-public.intel.com/671474/udk-debugger-tool-user-manual-v1-11.pdf.
Building and running on the target platform causes execution to stop at the following message:

Updated SBL Performance Table: S1 = 692000000ns, S2 = 2179000000ns, OSL = 37000000ns

Then the download is interrupted. I don't understand why this is happening. Just a few days ago it was working and the log was as follows:

...
