Well, you might be running out of file handles, try to increase the
allowed number.
There is a change in NetBeans 12.2, that it does not necessarily closes
the Gradle Project Connection on every Gradle invocation as in the
previous versions.
Also newer Gradle versions started to do a lot of filesystem watch
operation which also eat file handles.
If you can't share the actual project you have you might be able to
share at least the gradle files with the project directory layout
skeleton. The number of files would be also good.

Greetings,
We've all played internet guy, so don't worry about it.
Macbook Pro (15-inch, 2018). 32GB RAM.
OpenJDK 15.0.1 and OpenJDK 11.0.2 both show the same issue.
1 gradle project that contains 3 gradle subprojects. Since this is a work
project, I can't provide a copy of it. I'll say that Netbeans 11.3 and 12.1
have no issues with having this project open. In fact, those versions can
allow me to have 10 or 15 projects in the projects window with no issues.
I've configured Netbeans for a max heap of 8GB.
Netbeans freezes; Activity monitor doesn't show excessive CPU use.
I've attempted to attach jconsole to the running process with no information
provided.
I re-launched Netbeans 12.2 at work; while running junit tests, Netbeans
decided to freeze up and has now popped up a window containing "Too many open
files".
There's also a warning message in the output panel "No valid Java Platform
found for key: 'JDK_11'". That popped up just before the freeze, after around
5 to 10 minutes of Netbeans uptime.
I'll have to force quit Netbeans 12.2 just so I can get back to work.
An exception finally showed up, but the exception reporter cannot figure out
how to connect to the internet. And that specific notification is now gone
from the Notifications panel, so I can't even report it here.
There is something horribly broken in this release, IMO.
