Steps to reproduce

1. Update to VUE - Offical - 3.0.0-alpha.6
2. Start Windsurf
3. open a VUE file, 2 error messages are shown:

• The JS/TS language service immediately crashed 5 times. The service will not be restarted. This may be caused by a plugin contributed by one of these extensions: Vue.volar. Please try disabling these extensions before filing an issue against Windsurf.

• The Vue server crashed 5 times in the last 3 minutes. The server will not be restarted. See the output for more information.

What is expected?

Windsurf is loads the extension normally

What is actually happening?

VUE Official is crashing

Link to minimal reproduction

No response

Any additional comments?

Switchting back to 3.0.0-alpha.2 is fixing the problem

[philipdalen]

Just experienced the same problem.

[Nicholaiii]

Can confirm this issue. Disabling volar solves it, as does reverting to v3.0.0-alpha.2 - maybe these should be marked as pre-release in the marketplace before pushing them to clients? :)

Edit: I'm not on Windsurf, but VSCodium (spoilered build data)

i have the same issue, i had to install version 2.2.10 in order to work

[KazariEX]

Please download the newest vsix from here #5261.

[damms005]

@KazariEX any hope it'll be available in open vsx registry rathern than just installing vsix files?

[KazariEX]

This is my mistake, the next release on ovsx should be able to run normally.

[damms005]

@KazariEX any idea about possible date estimate for the ovsx release you mentioned?
