Hello everyone,

Since Christmas we are trying to solve a following problem, which happens on each of our servers, doesn't matter which version of Jenkins or plugins or even Windows version - Jenkins keeps failing when we want to modify the project, even if it's just a modification of the comment of project. By failing I mean saving the project and after ~30 sec getting the message "connection was reset" or similar, depending on the web browser. I tried different browsers, computers - every time is exactly the same.

After some investigations done via Chrome's inspection feature I realized that behavior is caused by a function checkpointLabelCheck, which provides the error "Please specify a label for this checkpoint!" if function was called without parameters (on server no. 22); if it was called with parameters, it just hangs (on server no. 19). This function belongs to the Jenkins plugin "PTC Windchill RV&S CM". If I disabled the plugin, everything works as expected.

Updating the Jenkins and plugins helped us for just few minutes - then the issue is exactly the same. Monitoring of logs haven't brought any results.

The only one suspected thing is installation of some Windows updates on 26/12/2021: KB 5008207 and KB5007152.

Could you help us to solve the issue, please?
Thank you in advance
