Issue when opening report from report server (build 15.0.1104.264 / 11/18/2020)

[Anonymous]

I recently updated  PBI Report Server and PBI Optimized for Report Server (build 15.0.1104.264 / 11/18/2020)

I have about 5 reports on the server, and usually open 2-3 at the same time by clicking right mouse button on the report, Edit, than PBI Optimized for Report Server opens, than manually click refresh, wait to refresh, Save. But with this version sometimes, not always, when I click on Edit on one of the reports PBI Optimized for Report Server opens and this screen appears( look like there is no visual report and PBI offers me to select and drag fields):

Workaround: I open the report a few more times and suddenly the report opens correctly. This issue happens randomly, it's not connected with specific report, most usually happens when I open more than 2 report from the report server and the same time.

I also have similary problems with new PBI Desktop version. I generally not have problem open more reports from PBIRS at same time. But new version is much less stable than prev versions. My PBID is crashing randomly several times per day, and crasing in situations when previous versions neverer crashed.
