Got illegal instruction crash when running fuzzilli on Wsl2 Ubuntu 22.04. Does fuzzilli support Wsl2?

I've just tried it on my Windows 10 machine using WSL2 with Ubuntu 22.04 with

$ swift run -c release FuzzilliCli --profile=v8 /path/to/d8 --storagePath=/tmp/fuzzilli --jobs=16 --overwrite

and it's been running for multiple minutes without any issues.

I tried new swift version and it works fine now! Now the d8 binary fails with some initial test cases

[JavaScriptEnvironment] Have 8 custom property names: ["d", "c", "e", "g", "h", "f", "b", "a"]
[JavaScriptEnvironment] Have 6 custom method names: ["o", "toString", "n", "p", "m", "valueOf"]
[Fuzzer] Changing state from uninitialized to corpusGeneration
[Fuzzer] Initialized
[Fuzzer] Testcase "fuzzilli('FUZZILLI_CRASH', 0)" did not crash
[Fuzzer] Shutting down due to fatal error

I tried the command swift run REPRLRun to debug, here is the output:

Looks like the status is different from the Linux version, it should returns 5 here. However spidermonkey works fine.
