Vivaldi browser still wont start (clone syscall)

[iz0eyj]

I goth the new build 14915, some issues are solved but still a bit of work to do.
this is the new strace:
clock_gettime(CLOCK_MONOTONIC, {183, 37642000}) = 0
access("/opt/vivaldi/vivaldi-sandbox", F_OK) = 0
socketpair(PF_LOCAL, SOCK_SEQPACKET, 0, [6, 7]) = 0
shutdown(6, SHUT_RD) = 0 *** WSL 14905 CRASHES HERE ***
shutdown(7, SHUT_WR) = 0
pipe([8, 9]) = 0
mmap(NULL, 8392704, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS|MAP_STACK, -1, 0) = 0x7f125a660000
mprotect(0x7f125a660000, 4096, PROT_NONE) = 0

stat("/opt/vivaldi/vivaldi-sandbox", {st_mode=S_IFREG|S_ISUID|0755, st_size=14528, ...}) = 0
access("/opt/vivaldi/vivaldi-sandbox", X_OK) = 0
pipe([12, 13]) = 0
close(13) = 0
rt_sigprocmask(SIG_SETMASK, ~[RTMIN RT_1], [], 8) = 0
clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0x7f1266cb0cd0) = 215
