i basically cloned the geeksforgeeks simple browser (https://www.geeksforgeeks.org/creating-a-simple-browser-using-pyqt5/) and made changes to it so this also behaves the same also i think microsoft made some changes to site as it worked fine yesterday.

can someone help me solve this i wanted to get url of app from the site.

Well I found the answer to my issue, the answer was just to upgrade to the latest pyqt6(https://pypi.org/project/PyQt6/) and use pyqt6-webengine(https://pypi.org/project/PyQt6-WebEngine/), the pyqt5-webengine was implemented using chroimium 87 and the pyqt6-webengine was implemented using chromium 90 (https://wiki.qt.io/QtWebEngine/ChromiumVersions) which automatically upgrades http requests to https.

in pyqt5 i got this error

js: Mixed Content: The page at 'https://www.microsoft.com/en-in' was loaded over HTTPS, but requested an insecure image 'http://arc.msn.com/v3/Delivery/Events/Impression?PID=425107905&TID=700346678&CID=128000000003037669&BID=1794732536&PG=PC000P0FR5.0000000IQX&TPID=425107905&ASID=001880bd94094f85a068a36faf64dcc8&BCNT=1&PG=PC000P0FR5.0000000IQX&UNID=318922&MAP_TID=14964BA1-C3BA-47F4-9E0C-84F0E8F87A52&ASID=FD46F1A327D7474EBFE5E7A37D3D2ABC&REQASID=FD46F1A327D7474EBFE5E7A37D3D2ABC&ARC=1&EMS=1&LOCALE=EN-IN&COUNTRY=IN&HTD=-1&LANG=16393&DEVLANG=EN&CIP=52.230.41.54&ID=3E20CD16E70260B91F34DC64E6B06116&OPTOUTSTATE=0&MARKETBASEDCOUNTRY=IN&CFMT=&SFT=GIF%2CAGIF%2CJPEG%2CJPG%2CBMP%2CPNG&H=320&W=240&FESVER=1.3&DEVFAM=WINDOWS.DESKTOP&ARCH=X86&APIVER=7000&AS=T&AS1=T&AS2=T&CHNL=CFD&UIT=G'. This content should also be served over HTTPS.
process is terminated with return code 3221225477.

Which i am gussing means it was unable to process the request as it came as an http request and the site ran https so due to this the app crashed since pyqt5-webengine (old version of chromium) didn't upgrade http request to https automatically.

after upgrading to pyqt6

js: Mixed Content: The page at 'https://www.microsoft.com/en-in/' was loaded over HTTPS, but requested an insecure element 'http://arc.msn.com/v3/Delivery/Events/Impression?PID=425107905&TID=700346678&CID=128000000003037669&BID=1368990958&PG=PC000P0FR5.0000000IQX&TPID=425107905&ASID=595dbd04fa15459fa34c9c2e09767c7f&BCNT=1&PG=PC000P0FR5.0000000IQX&UNID=318922&MAP_TID=5E7FABA2-C730-4EE2-8234-FF66A1A9BB9D&ASID=30465AA3C164432A80ECBC230628569F&REQASID=30465AA3C164432A80ECBC230628569F&ARC=1&EMS=1&LOCALE=EN-IN&COUNTRY=IN&HTD=-1&LANG=16393&DEVLANG=EN&CIP=52.230.41.54&ID=064BAED440726CB73AFABF7541856DF7&OPTOUTSTATE=0&MARKETBASEDCOUNTRY=IN&CFMT=&SFT=GIF%2CAGIF%2CJPEG%2CJPG%2CBMP%2CPNG&H=320&W=240&FESVER=1.3&DEVFAM=WINDOWS.DESKTOP&ARCH=X86&APIVER=7000&AS=T&AS1=T&AS2=T&CHNL=CFD&UIT=G'. This request was automatically upgraded to HTTPS, For more information see https://blog.chromium.org/2019/10/no-more-mixed-messages-about-https.html

so after i changed to pyqt6 the same error came but instead of crashing and giving me the error code it automatically upgraded the request to https (since it uses more recent version of chromium). i think if you are somehow able to make pyqt5 use latest version of chromium it should work but i dont know if its possible or how to do.

Feel free to correct me if i am wrong. I am not an expert in python or pyqt but this solution of upgrading to pyqt6 worked for me and solved my issue.
