When I follow the steps you gave, the following problem occurs when I run CrossFuzz.py for the first time. How can I modify it to solve this problem?

Hello, @ChinaWaldeinsamkeit. The issue is with this line:

File "/home/ubuntu2004/CrossFuzz/fuzzer/utils/utils.py", line 89, in compile
solcx.install_solc(solc_version)

This line of code is used to download the solc compiler. I believe it might be a network issue; I suggest trying it a few more times :)
