Alright, been plagued by this for weeks, I'm also open to all other debugger suggestions for dynamic debugging that does it in a manner CE does. I read through many other related topics but to no avail.

The app becomes unresponsive and eventually crashes as soon as the debugger is attached regardless of what app I attach the debugger to, sometimes giving "All registers are used up. Free some and try again" error, and other times not. Using CE 7.5 and ceserver 7.5:

I first tried CE in 32 bit Bluestacks, and I guess that's the worst possible emulator for this anyway, then moved onto Nox as is suggested in other threads.

In 32 bit Nox emulator running on Android 7 and using ceserver_x86, this time CE managed to get several readings from Find Out What Accesses This Address right before crashing the app again.

In the final attempt I set up 64 bit Nox simulator running Android 9 and installed ceserver. Though for some reason it did not run ceserver_x86_64 giving this error message:

process_vm_readv=0x79feb1c002b0
process_vm_writev=0x79feb1c002d0

CESERVERPATH=/system/xbin/ceserver_x86_64/
Segmentation fault

So then I initialized ceserver_arm64 instead, crashing the app all the same. ADB Shell fills up with error messages as the debugger tries to attach to process , here's the same repeating error message on the Shell until crash. It somehow looks like Android OS is trying to fight back the debugger:

Simple scans and modifications to memory work just fine so long as debugger isn't involved. I also tried changing breakpoint and debugger methods in CE settings. Any help is greatly appreciated.

compile ceserver from the sourcecode (and the client as well)
