Hope u have generated the crash with below patch,
https://source.codeaurora.org/quic/qsdk/oss/system/feeds/wlan-open/tree/mac80211/patches/019-ath11k-disable-q6-recovery-to-crash-kernel.patch?h=win_ap.1.0

Please remove this patch to see the target recover after the crash.

John also pointed me to this patch yesterday and I have now removed it.

But the wifi hardware doesn't recover after issuing an assert. All(?) 
firmware
request will just timeout:

ath11k must be unloaded + loaded again to fix this problem.

Could you plz try removing below patch?
