RB750Gr3 - ssh bug?

Hi Mikrotik team,
I might have found an issue with ssh keysize → routeros crash.
RB750Gr3
ros v6.38.5, firmware 3.35

terminal-> ip ssh
set strong-crypto=yes
set host-key-size=8192
regenerate-host-key

then I did soft reboot (system->reboot) and system didn’t come up. Reset button didn’t help. Only thing that helped was netinstall. With key size 4096 it works correctly.

Thank you.
