Latest Microsoft Windows 10 - 2004 ver. update issue using HDR

After installing the latest Windows 10 2004 update released on 16/10/2020 when i zoom any display using the Alt-Gr keys the windows stays blank and all buttons stop working and need to terminate the program. This happens when using HDR only with my Radeon Rx5700 with any driver version. To stop the issue i had to disable HDR. This never happend before yesterday.
Tested with A320 Neo no Mod and latest Radeon drivers and Whql drivers.
Forgot to mentions that another way to avoid the issue is keeping the VFR map off while Hdr is on.
