I have new code that I tried to run on esp32 and failed. I loaded a code that used to work before and now during compile I have ‘lv_font_montserrat_48’ was not declared errorr and suggest to use the montserrat_14. I used 5 different size font and worked before in each of my sketches.
I tried the latest version in Arduino and reverted back to V3.3.6 but the results are the same. I set it to this version as I use the same in SquareLine Studio the same version. This used to work on previous versions.
This is a snipped of the code for a roller widget
// ROLLER
static lv_style_t style_sel;
lv_style_init(&style_sel);
lv_style_set_text_font(&style_sel, &lv_font_montserrat_48);
static lv_style_t style_def;
lv_style_init(&style_def);
lv_style_set_text_font(&style_def, &lv_font_montserrat_34);
both fonts triggered the same error and all of these fonts are enabled in the lv_conf.h heather file. I use other fonts too at different widgets and every font came up with the same error.
This is the error I get, do not worry about the SPI HOST problem that is a simple change as I switched to different esp32 to see if I get the same error for the fonts and got the same with different esp32 as well.

Is LV_FONT_MONTSERRAT_48 enabled in lv_conf.h?
yes, all the relevant fonts are enabled that is why I do not get what is happening.
Just as test, please try adding this in your main.c:
#if LV_FONT_MONTSERRAT_48
#error "ENABLED!"
#endif
You can also try
- cleaning and rebuilding the project.
- add
#error "ENABLED!" to lv_font_montserrat_48.c` to see it’s really enabled
