[SOLVED] Frequent BSODs with the cause Bad Pool Caller

For several weeks now, both PCs in our household have been crashing regularly. Each time the reason is "BAD_POOL_CALLER".

Both systems have clearly different purposes. One is used for work and has mainly office and work software installed. The other is mainly for programming and gaming. Both PCs have an Intel CPU, but only one has an Nvidia graphics card and the other has intigrated graphics. Both PCs have current drivers and all Windows 11 updates installed. However, both PCs have Avira Prime installed with all features (speed-up, antivirus, VPN, etc). So my only guess is that it may be due to Avira.

I have already tried to find the error with WinDbg Preview. However, the only thing I could find out was that the problem seems to come from NETIO.SYS.
Unfortunately, that was all I could find out with the tutorials from the internet and hope you can give me tips on how to find the reason for the crash.

The EventLog had the following error before the kernel power error (Critical):
This is the first instance of the error seen during this time period on Storport Device (Port = 0, Path = 0, Target = 1, Lun = 0) whose Corresponding Class Disk Device Guid is {00000000-0000-0000-0000-000000000000}: The request opcode was 0xA2 and completed with SrbStatus 0x4 and ScsiStatus 0x2. The sense code was (0x5,0x24,0x0). The io latency was 1 ms.

The WinDbg log looks like this: https://pastebin.com/bvKdYTg2

Thanks for any help!
