Dear sir, from some days ago I'm facing issues on updating a specific application that I'm used to make almost weekly. I grab the apk from the same source always which is WhatsApp web site on the android section. I download it from vanadium and never had any issue installing it even from vanadium and from files applications
Now this week on my daily routine it simply not installing anymore as I will show above.
The most curious is that the uodate fails only in the latest version of the OS on a PX9 XL Pro. I have a PX10 Fold with the same version and configuration of the P9 and I can without any issue apply the update.
All installation in both models are made in secondary profiles with all installations access granted.
This is the website I always perform the update:

This is confirming the permission granted on vanadium but it was granted to the user on main profile also

This is the update confirmation

This is instantly shows after the fail

Otherwise on the FILES app the samething happen but appear a message which I'm not remembering have seen in no updates before. The same installation grant is enabled before installing the pkg. That the warning I never saw before. Maybe I had never paid attention but I'm not remembering see this before.

I click on continue (continuar)
The confirmation screen appears

And the fail repeat.

Important things:
1 I cannot uninstall the already installed version because my WhatsApp is a highly targeted app for attacks and in this process of reinstalling and re register the adversary can unregister my account take over it as he done multiple times
2 the installation update occurs successfully on a device with same configuration, version, everything, including the secondary profile. Its literally a copy of one from other being the only difference the model.
Can anyone help on this because doesn't make sense that a week from now this is happening. I thought could be android sideload restrictions but I don't even know if its implemented on grapheneOs and if is wouldn't make sense that works on a device and not in another considering they have the same configuration.
I appreciate all for the help.
Thank you
