Hello @Mohammad Aboulhassan

My first suspicion (error stack suggests) that you need to update your system- especially your graphics card.

Although you might update your Win application regularly - sometimes not all updates are actually installed and other applications are not updated at all.

Please follow these Wiki Articles (Part 1 and Part 2) regularly rebooting between steps

https://community.sdl.com/product-groups/translationproductivity/w/customer-experience/3392/how-to-part-1-trouble-shoot-unexplained-errors-and-unwanted-behaviour-in-studio-multiterm

Please let me know if this helps.

Thanks a lot, Steven.
As I told you my system is updated regularly as well as my device drivers, I have the Intel driver updater software installed, which checks regulary for new updates and installs them.
I made a manual check, my drivers, including my Graphics drivers, are up-to-date.

I am now trying to to disable some App store plugins, maybe  it's one of them!

Now things are getting worse, it crashed suddenly while working.

Any suggestions?

Hello Muhammad Abulhasan ,

I found a similar case from a while back

https://community.sdl.com/product-groups/translationproductivity/f/openexchange_applications/21001/studio-2019-shuts-down-by-itself

Maybe try resetting Studio will help

If not, please log a support ticket (selecting 'Submit Case'

https://gateway.sdl.com/liveagentlicensing

Once this has been resolved, please let us know what helped in this instance.

Thanks Steven,
I forgot to tell you that I already tried the reset solution, but unfortunately it didn't work, actually the last crash happened after the reset.
I removed most of the plugins, keeping only 2 or 3 that I mostly use, still the same.

I'll try turning off Uplift and see it it works.

I am having the same thing! Ever since I installed this cumulative release, I am facing all sort of error messages. That is a real pain to say the least.

even the TTS plugin stopped working again for me. Paul Filkin is very much aware of this issue because we spent a lot of time addressing it before with the developer.

I'm aware of it because you sent me the error stacks through whats app a short wile ago.  We have not addressed this with the developer at all.

We have spent some time investigating this and so far we can't reproduce it at all.  So we're not sure where the problem is coming from. I'd recommend that you both log a support case.  If you don't have a support contract please use the web to case link:

Hello everybody,

Update: I freshly installed everything (Windows, Studio and everything else) and It's been so far so good with Studio. I hope it stays that way.

I'll keep you posted.
