I dumped the output of load_pw_modules.sh to a log file, there's one error that stands out:

+ pw-cli -m -d load-module libpipewire-module-xrdp sink.node.latency=2048 sink.stream.props={node.name=xrdp-sink} source.stream.props={node.name=xrdp-source}

Seemingly pw-metadata -n settings 0 default.clock.quantum 4096 returns an error.

However, after that I tried to run the commands above, and this time no error:

┌──(kali㉿kali)-[~]

Maybe there's a race, since as we can see here:

pipewire-module-xrdp/instfiles/load_pw_modules.sh

Lines 46 to 53 in e9c6c05

 # enable both xrdp-sink ans xrdp-source 

 $PWCLI -m -d load-module libpipewire-module-xrdp-pipewire sink.node.latency=$QUANTUMVAL sink.stream.props={node.name=xrdp-sink} source.stream.props={node.name=xrdp-source} > /dev/null & 

 # enable xrdp-sink only 

 # $PWCLI -m -d load-module libpipewire-module-xrdp-pipewire sink.node.latency=$QUANTUMVAL sink.stream.props={node.name=xrdp-sink} > /dev/null & 

 # enable xrdp-source only 

 # $PWCLI -m -d load-module libpipewire-module-xrdp-pipewire source.stream.props={node.name=xrdp-source} > /dev/null & 

 sleep 1

pw-cli -m -d load-module is called and sent to background, and then we have a sleep 1... So maybe the pw-metadata commands are called too early after that....

I tried a few times to log in and out, and it's not 100% reproducible. Sometimes there's no error, sometimes there are more errors, and the output suggests that, for some reason, we don't get stderr in time, so we don't know which command caused it. Example:

+ pw-cli -m -d load-module libpipewire-module-xrdp sink.node.latency=2048 sink.stream.props={node.name=xrdp-sink} source.stream.props={node.name=xrdp-source}
+ pw-metadata -n settings 0 clock.force-quantum 2048
+ pw-metadata -n settings 0 default.clock.force-quantum 4096

It's all a bit confusing.
