Program crashes when changing the language with the <ctrl> <shift> key combination (RT 5.7 - 5.8)

Hello. For two versions of the program RawTherapee 5.7 5.8, I have been seeing a crash when using the key combination (to change the keyboard layout between English and Russian). The program crashes. Closes without messages. I am in the editor window. If someone knows the solution to the problem, please help me. Thanks.

What OS version?

i believe the ctl-shft keyboard switching funtion is in Windows.

Windows 10 Enterprise LTSC 1809 x64 (OS Build 17763.1098)
