linear mixed model not completing analysis

[MichaelLinguist]

Hi,
I'm running a mixed effect model on a large (178813 rows) data frame with Jamovi 2.6.44.0 for Mac. I am able to get a completed analysis when I use random intercepts, but I can't with random slopes. The analysis just keeps running and never completes. I'm using

Any ideas?

I updated to 2.6.45 and tried on the web with no success. Thanks in advance.
