Hey, sorry it took me a little longer to troubleshoot as I could not find why it broke the game till now. So I think I found the conflict that breaks the game in a blank project.
if I use the escape code \^ (to progress text without player input) in the text box the game gets stuck and it hangs, and my CPU usage jumps and I can't quit the game unless I use the CTRL + ALT + DEL task manager. If I don't use this \^ Escape code the game works and it displays text just fine even with the lighting plugin.
The compatibility issue with Galv's Message Styles (MZ Message Styles | Galv's RPG Maker Scripts & Plugins (galvs-scripts.com)) plugin remains though, where it draws text overlapping in weird ways multiple times. I think it may have something to do with the need to use the esc code "\pop[t]" at the start of the text box to activate the pop up window.
Any help you can spare for the above would be amazing! Thank you.
