error E491 in C++ files

[gtarabat]

Hello!
I get the following error when I try to jump to a definition in a C++ file.

Error detected while processing function <SNR>58_Jump[32]..search#SearchDefinitions[33]..<SNR>141_RunRgDefinitionSearch[8]..<SNR>141_ParseRgResults:
14939 line    7:                                                                              
14940 E491: JSON decode error at 'regex could not be compiled with either the default regex engine or with PCRE2.'

I am on Ubuntu 22.04 with vim 9.0 and ripgrep 13.0.0.

I get the same error with ag. No errors in Python files.
