Can't type the letter 'ü' in Adobe XD

Title says it all. When editing text in Adobe XD I can't type the letter ü/Ü.

My keyboard is a US ISO keyboard, it uses the US International keyboard layout within Windows, Windows itself is set to english, Adobe XD is also set to English.

I have to use the US International layout because that's the only way I found to be able to even type üÜ äÄ öÖ and so on (and yes this is a problem since I'm german). It uses the keyboard combination right_alt+y for ü and shift+right_alt+y for Ü. Both ä and ö work just fine within XD, it's really just the ü. It works fine outside all other programs without having to quit XD. This problem existed for quite some time now so I finally decided to write a post about it.

The only workaround I found is copy pasting from another window which is more than tedious.

I have ofc restarted XD, restarted the PC, reinstalled XD, reinstalled the Creative Cloud and so on. I'm certain that it's a bug within the software.

Hope you can help and thanks in advance!
