When we analyze lotus road enters deliberately, due to the specific obfuscation used in it, we repeatedly create the same basic blocks, eventually leading to OOM

Research direction
Load lotus road enters deliberately as windows-x64 with base 0x0 and reproduce the OOM. Investigate the analysis path that repeatedly creates basic blocks; done means the sample no longer creates duplicate blocks indefinitely or exhausts memory.
