<p>I also ran into this issue since July 2019 on a Windows 10 1903 acting as the client machine. The following workaround on the client works for me, so that RDP no longer freezes.</p>
<p>Start an elevated invite de commandes (run cmd.exe en tant qu’administrateur), and<br>
then run:</p>
<p>reg add “HKLM\software\policies\microsoft\windows nt\Terminal<br>
Services\Client” /v fClientDisableUDP /d 1 /t REG_DWORD</p>
<p>After that, close and reopen all your RDP sessions on your client computer to restart the Remote Desktop Client (mstsc.exe, aka Microsoft Terminal Services Client) application.</p>
<p>I’m waiting for a final fix to this issue.</p>
<p>Follow-up: I am not sure, but it looks like fixed in 21H1 (both client and server must run 21H1 or higher). For me I no longer see freezes without the disable UDP workaround.</p>
