Some of the host key presses are not matching with what remote perceives (Turkish Q keyboard)

Bug Description

I'm using RustDesk on my laptop running Windows 11, and using it to connect to my Ubuntu cloud instance. Some of the very vital keys to my usage are simply not registering as intended. I did a lot of debugging; messed around with keyboard layouts, re-installed stuff, tried different hosts (MacBook Air, Netbook with Windows 7), tried all keyboard modes (Legacy, Map, Translate), etc. but nothing helped. Combined with the fact that this issue does not occur with another software like TeamViewer or when I use VPN + Windows RDP, tells me that this is a software issue.

Keys that are switched up (out of all the keys on my keyboard):

• "Left Arrow" triggers "Alt R"
• "Down Arrow" triggers "Super R"
• "Right Arrow" does nothing
• "Up Arrow" does nothing, but attempts to take a screenshot
• "Control R" triggers "Page Down"
• "Alt R" triggers "Alternate Enter" (on the Numpad)

Rest of the keys are working just fine. As an additional note, even when I don't touch my physical keyboard and use the On-Screen Keyboard utility of Windows, output is the same.

How to Reproduce

Press one of those mismatching keys and observe.
(Vastly different hardware gives the same result for me, so I don't think host OS or hardware matters here.)

Expected Behavior

Proper matching of sent (by host) and received (by remote) keys.

Operating system(s) on local side and remote side

Windows 11 -> Ubuntu 22.04

RustDesk Version(s) on local side and remote side

1.2.3-1 -> 1.2.3-1

Screenshots

Additional Context

I have a Turkish Q keyboard, but this shouldn't be a factor regarding the problem because to re-emphasize, this does not happen with Windows RDP or TeamViewer.
