Power BI Desktop WebView2 Out Of Memory

Power BI is experiencing a problem with WebView2 running Out of memory. We have identified some of the top causes of this and have the details below. If that does not address your Out of memory problem, contact us at


Out of Memory cause: 

Custom visuals causing memory leak - If you are using any custom visuals and are running into Out of Memory crahses, please try removing the custom visuals to check if it resolves the issue. If it does, please reach out with the visual which was cauing the memory leak so we can address it. 

If you are not using any custom visuals and are still running into this, it could be due to having a lot of report pages and visuals per page. This causes the browser heap memory to exceed the 4GB limit and crash. This is sadly a limitation of chromium. 

Possible workaround 

Status: Delivered

Hi all,


We've noticed your problem, most of this issue is related to report design, you can follow the advice given by the OP to troubleshoot; if the problem persists, you need to collect logs for further investigation.

Since community support engineers don't have that access, I would suggest opening a Support Ticket. If you are a Power BI Pro or Fabric licensee, you can create a support ticket for free and a dedicated Microsoft engineer will come to solve the problem for you. 
It would be great if you continue to share in this issue to help others with similar problems after you know the root cause or solution.

Hi everyone,


one solution is at this link :


On my side, I've created a system environment variable before restarting powerbi desktop and it worked!


Environment Variable : "PBI_enableWebView2Preview"
Value: "0"


If everyone else can confirm.

I have come across the same issue which has been causing me major grief the last few days. I couldn't make any changes to my report since when I try to open up an existing Power BI file, it loads for a few minutes and then crashes with this error before it can finish loading. I'm using the Dec version. Very frustrating. Please advise!

Hi, it seems that some updates make this trubble. I reinstall the BI, maybe 5x times, then it works. Sometimes there is an update very soon which fixes this. Lukas

Just experience this error on desktop. The Power BI froze for about 5 minutes and then it quitted automatically.

Sorry ladies, gentlemen of MS:

We are getting this error in Power BI Desktop, by simply clicking on an edit request for a Power Automate script.

So I don't see the link whit Chromium or even Web browsers at all.

Just happened again. I was not doing nothing fancy, just editing some dax and suddenly PBI crashed and the Webview error mesage sending to this post showed up.

As GosselinGroup mentioned on 6/15/2022, I too experience this out-of-memory error when (only) using Power BI Desktop to create a Power Automate flow to send an email.


In Edit/Power Automate, when I create a new operation/step after the 'On Power BI button clicked' operation/step, I can successfully select and run the "Send an email notification (V3)" operation/step.


When I create a new operation/step, after the 'On Power BI button clicked' operation/step, I cannot successfully select and run the "Send an email (V2)" operation/step.


Power BI Desktop freezes and, approximately, 10 to 15 minutes later, the following error message displays and Power BI Desktop closes.

I have been experiencing the out of memory bug without any 3rd party visuals, and then, while trying the experimental field parameter feature had PBI crash on me...
