Installing issues with doom emacs

[k1nase]

I encountered quite confusing issues trying to install latex-preview-pane on Doom Emacs.

Installing the package with M-x package-install works perfectly, then activating the M-x latex-preview-pane-mode is ok, it works and everything is OK.

Since I quit Doom Emacs. When I launch it again after, the package is still installed but the latex-preview-pane-mode doesn't work anymore.

I tried with or without a doom/reload or a doom/sync, and with or without adding the (latex-preview-pane-enable) in my .emacs.

I am quite confused by the situation, tbh.

Using Emacs 27 with Doom Emacs 3.0.0 and the package reference is 20181008.1822
