Apache Module - Bandwidth Mod (mod_bw)

When using mod_rewrite to run a PHP script that inserts an X-Sendfile header to be use by the mod_xsendfile module, mod_rewrite is invoked a second time for a subrequest during file path validation. That's fine but the second invocation causes the hook (handle_bw) to add the bandwidth output filter twice. I haven't verified if that actually causes duplicate data on the wire but it causes BW to think there's twice as many connections, causing it to apply limits unnecessarily.
I've got a branch I'll submit soon with a fix, along with the PR. Hopefully that can be incorporated into the new version.
I'm trying to configure bwmod to work under debian, but no luck.
Here are the current settings:
Debian GNU/Linux 11 (bullseye)
Release: 11
Apache version 2.4.56
instaling ok:
apt-get update
apt-get install libapache2-mod-bw
enable ok:
a2enmod bw
setings under virtual host:
<Location "/">
SetHandler none
Order Deny,Allow
Deny from all
Allow from 192.168.11.100
</Location>
BandWidthModule On
ForceBandWidthModule On
BandWidth all 10240
MaxConnectionsPerChild 40
checking OK
apachectl configtest
Syntax OK
systemctl restart apache2
After that i have error 403 Forbidden You don't have permission to access this resource.
It is same error on all virtual hosts.
All permisions are OK.
apache error log have no error jus usual notice:

Can you try this kind of setup and make new release which is be working under debian 11?
Or I just doing something wrong ? :)
Here is the error, How can fix that?

I'm setting up a new server with mod_bw-0.92-2.4.x-x64-vs16 from ApacheHaus on Apache 2.4.51, on Windows Server 2019. I just discovered that with mod_bw enabled, files download very very slowly, far slower than the specified bandwidth. The server has a 10 gig interface. The bandwidth specified is very large (250 MB/sec), as I'm just trying to prevent multiple simultaneous downloads from overwhelming the interface.
Any ideas on the cause? I've tried various values for the packet size and lowered the bandwidth to 250 KB/sec (just took 3 zeros off the end). As the server is not in production yet, my test download was the only active session.
These are my settings:
BandWidthModule On
ForceBandWidthModule On
#Limit overall server bandwidth to 3 Gpbs (which is actually 375 megabytes/sec)
BandWidth all 375000000
MinBandWidth all 0
BandWidthPacket 32768
#Limit large file (more than 10mb) transfers to 2Gbps
LargeFileLimit * 10240 250000000
I saw a post mentioning issues with timing resolution in Windows. Could that be the cause?
