MIUI 14 problem can't install from unofficial channels

[spshl505]

Hey guys I updated my device to MIUI 14
But I can't download many programs and tools. A message appears saying: can't install from unofficial channels.
Please help me with that

Yes, don't try to update patched system apps with official ones on our ROMs.

Even programs such as the modified WhatsApp refuse to be installed. Is there a solution?

Make a log while trying to install it, and I'll tell you what the issue is.
