Description
Hi! i got some trouble with hbbs.exe.
i try it on Windows 10, everything is great! but on windows server 2019 hbbs.exe sets CPU load 100%. sometimes hbbs.exe works fine 5-10 mins, but then CPU 100% load.
hbbs.exe runs in cmd.exe, not installed service. i try to run it "hbbs.exe -r 127.0.0.1", to get no client connection. but geting 100% CPU load. i try nssm install servive, but result is same.
i try it in guest windows server 2019 in Hyper-V, on 2 different hyper-v hosts.i try it on different physical PCs. but everytime 100% CPU load.
i can try another build windows server 2019, but in production i cant reinstall it.
guest windows10 on the same Hyper-V host + same VM settings works great, no problems!

Research direction
Start by reproducing the report with hbbs.exe on Windows Server 2019, including the -r 127.0.0.1 invocation and the command-line setup. Compare its CPU behavior with Windows 10 and the reported Hyper-V configurations; done means the cause of the sustained 100% CPU usage is identified and a verified resolution is available.
