<div class="moz-cite-prefix">FWIW, this total system crash has been
isolated to the kernel. Kernel 5.17.5-76051705 crashes. Which
was pushed out to apt on, guess what, May 26, 2022, the date my
computer went to hades. <br>
</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Kernel 5.15.0-37-generic does not
crash. Kernel 5.18.2 also crashes, only if I use TyCommander, but
not necessarily during a USB flashing. I had 5.18.2 crash while I
was using Firefox, but while Arduino IDE and TyCommander were
active.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Now running on 5.15 and things are
stable.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">I know nothing about kernels and stuff
like this. Been forced into it. An average Joe like me shouldn't
have to deal with this kind of thing. <br>

<div class="moz-cite-prefix">TyCommander works fine on an RPI4
running Raspberry Pi OS 64 bit, which as I understand it is a
Debian derivative. The kernel is 5.15.30, according to
Wikipedia. Not looking forward to an update of that kernel.</div>

In particular, specify what hardware you have, and the software you're
running, in one place. If it's a scavenger hunt just to find that
information you'll get a poor response. I didn't see any mention of
the model of machine, for example. List major components with model
or type (CPU model and speed, RAM size, type and size of storage,
model/type video controller, etc.). You mention distribution and
version, which is good, but also please provide kernel version. Also
include steps to reproduce (when it happens, when it doesn't),
commands you've tried, places you've looked for files, error messages
received, etc., etc.
I know you've been around long enough that you've seen plenty of bug
reports and knowledge base articles and the like. Follow their
example.
