Permission Denied Error on version 1.3.0 and 1.3.2 when connecting flipper with qFlipper

[hack-wizard]

Describe the bug
qFlipper fails to connect on Debian 11 over USB, I've tried the old version (which seems to have stopped working) and latest release 1.3.2

To Reproduce
Steps to reproduce the behavior:

1. Run qFlipper as root (sudo) via terminal (also ran the rules install command first, it confirmed they were)
2. Ensure Bluetooth is off on flipper
3. Connect flipper from any USB port
4. I get the permission denied image
5. Terminal shows it repeatedly tried to connect to serial port at /dev/ttyACM0
6. If I click READ MORE I get an error saying Parameter "link' is not declared

Expected behavior
The flipper properly connects and I can update firmware/manipulate the filesystem

Actual behavior
It acts as though it cannot figure out how to initiate the serial connection

Additional troubleshooting

1. I rebooted, tried different cables and ports and even closed all browser windows.
2. using command screen /dev/ttyACM0 115200 connects over the flippers serial port, proving the flipper itself isn't the issue
3. Also tried reinstalling the rules and confirming my user is in the dialout group

Put this
SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="5740", MODE="0666", GROUP="plugdev"
in a file like
99-flipperz.rules
under
/etc/udev/rules.d
and restart udev with
sudo udevadm control -R
.
Add your user to the group plugdev.

[hack-wizard]

Created that file, added what was requested, restarted udev, added user to the group and... that had no impact.

Should I have added this line to /etc/udev/rules.d/42-flipperzero.rules by any chance? That's what I have in the directory specified

EDIT:
I tried adding it to /etc/udev/rules.d/42-flipperzero.rules as shown below

#Flipper Zero serial port
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="5740", ATTRS{manufacturer}=="Flipper Devices Inc.", TAG+="uaccess", GROUP="dialout"
#Flipper Zero DFU
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", ATTRS{manufacturer}=="STMicroelectronics", TAG+="uaccess", GROUP="dialout"
#Add suggested by tinkercnc on Github - https://github.com/flipperdevices/qFlipper/issues/194
SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="5740", MODE="0666", GROUP="plugdev"

Issue persists and replicates, both for my user and root.
