etc ...
Originally the bug only occurred with 32-bit builds: ticket:1899#comment:2. But python-comtypes is so flaky that it looks like it's broken again, even on 64-bit now?
Can you set:
set XPRA_SILENCE_COMTYPES=0
Then run xpra with:
Xpra_cmd -d util ...
This should give a lot more details about what / where things are failing.
The comtypes bits are here:

This looks like an upstream bug: ModuleNotFoundError: No module named 'comtypes.gen.stdole'
The fix seems to be here: Fix importing newly-created modules on Python 3.
I will try to build a new comtypes package with this patch included.
Created a pull request: comtypes: include patch from upstream to fix missing module errors and I've uploaded a r25179 build with the updated comtypes package.
Does that work better for you? (the error is a race condition - so it may just come and go away on its own..)
Apparently, beta is missing the zip packages :/

I keep trying to downgrade to get a usable Windows client, but it's not happening - I keep getting flooded with:

Ooops, try now.
This fix is included in the latest 3.0.6 stable release for win32 (r25205). There are also beta 4.0 ZIP packages now.
I keep getting flooded with: (..) 2020-02-10 12:51:11,324 Error: failed to receive anything, not an xpra server?
Are you sure that the problem is client side?
Replying to Antoine Martin:

You are right: probably it hasn't connected at all:
$ ls -lah /run/user/1000/xpra/ total 8,0K drwx------ 2 u u 60 Φεβ 10 15:52 . drwx------ 14 u u 420 Φεβ 10 15:31 ..
I'll just try with the newest builds; no reason to keep with older builds I guess

IIRC, the latest 3.0.6 release builds also have this fix.
Xpra-Python3-x86_64_4.0-r24762 gives:
That's older than the fix. That said, there's no error in that output, which can happen since the bug was a race condition in python-comtypes.
Seems that Xpra-Python3-x86_64_4.0-r25205 is working all of a sudden :/
Also, this is now fixed.
It's happening again, and it looks like a comtypes bug:
2020-03-12 15:40:02,807 Could not import comtypes.gen, trying to create it.
2020-03-12 15:40:02,807 Creating comtypes.gen package failed: [WinError 3] The system cannot find the path specified: 'E:/Xpra/trunk/src/dist/lib/library.zip/comtypes/gen'

Because calling CreateObject("WbemScripting.SWbemLocator") should work: SWbemLocator.ConnectServer method.
The same code does work from an MSYS2 shell:
>>> from comtypes import CoInitialize
>>> CoInitialize()
>>> from comtypes.client import CreateObject #@UnresolvedImport
>>> o = CreateObject("WbemScripting.SWbemLocator")
>>> o
<POINTER(ISWbemLocator) ptr=0x9ff13d0 at 9f10e40>
So maybe it's just not happy when running from a memory-only package?
Unfortunately, python-comtypes is not very active at all, no releases since 2018... So maybe we'll have to use something else.
For now, r25617 makes this error less scary.
out of time
Not much happening with comtypes..
