Android Question App runs and then stops after few seconds on OPPO Android13 colorOS

[robotop]

Good morning. It's a very long time that I'm not here on the forum. Now I faced a very strange behaviour on a phone OPPO with Android 13 (colorOS).
I used the "standard" tools that I use since the beginning, when I started developing apps with B4A on a tablet with android 1.6 . Well... stop talking about the past.
The strange behaviour is that one App, just installed via B4A bridge runs and then stops (without a reason) after few seconds.
I tried also using the "debug" mode, but that doesn't work in any way. I also compiled the App using the option to have a log even in release mode, but I just had a message for application start (first time) and then no other messages when application was (by itself) closed.
I enabled, on the phone, the developer options and set also the usb debug, but nothing changed. No log messages, no debug mode (via B4A bridge).
I can't understand why the App (is a very old app) doesn't run as it do on other phones.
I also updated to the last version the colorOS on the smartphone and then the B4A environment, using target 33 as suggested.
Has anyone experienced the same problem ? Any help will be really appreciated, thanks.

try to connect he device with USB-Cable and use the IDE to install the app without bridge.
Check the unfiltered log if no log appears....

The first step is to get the logs working. Start with USB debug mode. If there are no logs then they are disabled on the system level. Look for a related setting under the developer settings.

@DonManfred and @Erel : Many thanks for your answers. At the moment I don't have the phone here, but I will try using the USB and report here the results.
Addendum: I tried to install the same App on another Android13 device and all worked as expected. Note that also the B4A bridge had a problem downloading the App on such colorOS (never ending). Also while trying to use the App in debug mode I faced a continuously rotating gif and the App wasn't open.
