Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
Yes. 5.0-12088.

Is the issue present in the latest stable version?
No.

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)
Nearly impossible to tell without access to bisect tool. :( The issue isn't present in the latest stable version.

What are your PC specifications? (CPU, GPU, Operating System, more)
Intel i5-9600k (base clock)
NVidia RTX 2060
Windows 10

Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)

As the beta is incompatible with 5.0 stable savestates, no. :(
