InDesign 18.5 very slow on launch and very slow on PDF export for M1 iMac 2021

[Ömer HARNAK]

InDesign 18.5 is very slow while launching and extremely slow while exporting a PDF. It is running on a Apple M1 iMac 2021 (With Mac OS Ventura 13.5). But it launches and exports perfectly fine on my MacBook Pro again with Mac OS Ventura 13.5 (which does not have a M1 chipset)
This is blocking my workflow. What should I do to fix this?

Very difficult to know what the issue is here.
