The latest release

https://github.com/netbirdio/netbird/releases/tag/v0.51.2

and especially the

netbird_installer_0.51.2_windows_amd64.exe

is unable to trigger the uninstall of the previous version due to when executing the binary, it triggers the Windows Defender ASR rule

https://learn.microsoft.com/en-us/defender-endpoint/attack-surface-reduction-rules-reference#attack-surface-reduction-rules-by-type

namely

"Block executable files from running unless they meet a prevalence, age, or trusted list criterion"

I hope there will be a quick fix soon!
