The strange bug causes my aircraft crash

dear all ,
please look the video,I performed a short flight from Urss to URMM. When APPROCHING, there was a messy flow. The height of DH suddenly appeared on the ground and Crash.
I have been using fsrealistic, GSX, SU11, DX12, why does this strange bug appear?

Pretty sure it may be the first update of FS Realistic with the walk about feature. Have you updated it?

100% FSRealistic, if you haven’t updated it, if you notice their changelog, there has been a bug where aircraft suddenly nosedive. Even though this was not a nosedive, this has happened to me the exact same way on short final as well. Once I updated, I have not had a problem with that anymore.

Is the latest update version 2.1.1?

Yup latest versions is indeed 2.1.1

Still happening. I just flew from KBOS to KATL and 5 miles out from the runway, while on the GS and LOC, my fenix a320 took a nose dive. Was no saving it. Im getting to where I dont want to use any addons. Seems they are always causing some type issue
