Thank you for reporting. Confirmed there is a bug here.
You may be able to work around the issue with the following instructions. Please let us know if it works for you:

Please use the following steps on your Kasm server, (or the WebApp role if using multi-server) in your ecosystem to receive the share server fix.

1. Open a terminal on your WebApp Server

2. Open the docker-compose.yaml file in an editor

sudo nano /opt/kasm/current/docker/docker-compose.yaml

In the kasm_share section, adjust the tag for the share container to 1.14.0-alpine in the image section and save the file:

image: "kasmweb/share:1.14.0-alpine"

It should look similar to this:

3. Stop the Kasm services

sudo /opt/kasm/bin/stop

4. Remove the exiting kasm_share container sudo docker rm -f kasm_share

5. Start the services

sudo /opt/kasm/bin/start

Log back into Kasm and start a new session, and toggle sharing on. Now hopefully the chat widget will function again
