Onboard virtual keyboard crashes after start

Hello!
I’m new in this site, but I wasn’t able to find any help searching thru Google…
I own a tablet pc and I’m trying to get onboard to work, but every time it just crashes few second after I run it.
Running it in terminal shows this error:

/usr/include/c++/12/bits/stl_vector.h:1141: std::vector<_Tp, _Alloc>::const_reference std::vector<_Tp, _Alloc>::operator[](size_type) const [with _Tp = unsigned int; _Alloc = std::allocator<unsigned int>; const_reference = const unsigned int&; size_type = long unsigned int]: Assertion '__n < this->size()' failed.
Aborted (core dumped)

I’m not familiar with coding…
How can I make it work in Fedora 36?
