[Any app containing ads] Crash due to ads and AdWorker

[MugoSquero]

Affected apps
Name: AIDA64
Package id: com.finalwire.aida64

Name: CPU-Z
Package id: com.cpuid.cpu_z

Describe the bug
Any app (I only tested aforementioned ones) trying to show ads crash.

To Reproduce
Just install one of the apps I provided and try for yourself.

Expected behavior
I don't know what to expect really. Do microg block ads or just contacts the Google for ads? The only expected behavior is that apps-with-ads to not crash regardless.

System
Android Version: 14
Custom ROM: Samsung A35 5g/Magisk root/signature spoofing

microG
microG Core version: 0.3.4.240913 (240913008)
microG Self-Check results: All ticked

Now, for some unknown reason, after a reboot, the AIDA64 app starts without problems, but the MicroG Companion app (vending) crashes.

Here is the exception log:

FATAL EXCEPTION: main

CPU-Z is worse. Both the app and vending crash (similar/same exception output).

MicroG Companion app version: 0.3.4.40226 (84022608)

I installed MicroG with MinMicroG minimal package. All installed as system apps. Any other app workes without problems (e.g., RVX). Passing the integrity check (done the test through the MicroG app).

Can someone please test one of the apps on their phones and see if they are working as intended?
