Wineserver crashes with wine-tkg-staging-fsync-git-9.21.r0.gf03d32e3-327

[MangoTCF]

The crash is consistent and happens when I do literally anything with wine.

mango in ~ λ wine cmd                                      
wineserver: using server-side synchronization.
002c:fixme:winediag:loader_init Wine TkG (staging) 9.21 is a testing version containing experimental patches.
002c:fixme:winediag:loader_init Please don't report bugs about it on winehq.org and use https://github.com/Frogging-Family/wine-tkg-git/issues instead.
wineserver crashed, please enable coredumps (ulimit -c unlimited) and restart.

How do I extract the coredumps to help with diagnosing the issue? (When i enable the coredumps, it just says nothing and exits)
