What happened:

The editor crashes on creating the new project while the editor is already running in the background, the crash frequency is more while naming new project with non-western characters.

Example:

Лорем ипсум долор
Λορεμ ιπσθμ δολορ
情米出則係療社優真学将
支ぐリ済治でてづら
법관은 탄핵 또는 ( *Project name input field doesn't recognize these characters)
بقعة وعُرفت الغالي بل وصل
ლორემ იფსუმ დოლორ
ÆØÅæøå
ĂÂÎȘȚăîâșț

Steps to Repo:

1. Open unity project > file > new project
2. Name project using non-western or western characters > create project
3. Observe editor crashes and bug reporter window opens-up also, the new editor instance launches successfully.
