InDesign 19.* crashing on Windows 10/11
Since version 19, I have encountered numerous stability issues, including crashes. I was unable to upgrade initially, but I discovered that moving the .indd file locally rather than on the network, while still keeping all other links on the network, resolved the problem.
I now work in this manner, and despite all subsequent upgrades (to version 19.3), I no longer experience any issues. I hope my experience can be beneficial to others.
