Help !!! Crashing Apps

I have a MacBook Pro 13inch, mid 2012 2.5Ghz Dual-Core Intel Core i5

And I am running MacOS Ventura using OCLP.

I noticed apps have been crashing during use specially when I use special keys(escape, back, forwards, alt, crl etc) It was bearable but now, I it has become frustrating.

Does anyone know how I can solve this problem?

Cheers
