What's the problem? Describe what went wrong.

When playing online the game will have an unrecoverable freeze, requiring a restart. Progress since the last save is lost.

What steps will reproduce the problem?

There isn't a consistent way of triggering them. Generally my frequency of freezing has been daily while keeping up with the latest dev version.

Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.

17271 is the latest tested with instability.

Is the issue present in the latest stable version?

Latest stable version is 17245, 20+ hours of gameplay without freezing.

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)

Somewhere between 17245 and 17271.

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too. For more information on how to use the fifoplayer, please check here: https://wiki.dolphin-emu.org/index.php?title=FifoPlayer

[Attach any fifologs if possible, write a description of fifologs and screenshots here to assist people unfamiliar with the game.]

What are your PC specifications? (CPU, GPU, Operating System, more)

Windows 10 Pro x64
Ryzen R5 3600
RTX 3060 Ti
16 GB RAM
512 GB SSD
Using GC adapter and GC controller

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

These freezes are usually suspected of being caused by network changes. PRs 10985/10920 may have changed network behavior in a way that increases freeze frequency. If back-to-back testing w/logging is possible, that might help confirm these PR are impacting network behavior on PSO.
Alternatively, re-testing 17271 but w/o those two PRs.
